Beyond their use in first-response setups, thermal imaging expands the range of tasks that robotic devices can perform in high-risk environments or emergency situations. Let's take a look at some of the "hot" topics related to thermal imaging and its applications.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 24px; font-family: Arial;"><strong>What is thermal imaging?</strong></span></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 22px; font-family: Arial;">Infrared thermal imagers can efficiently convert heat (i.e., thermal energy) into visible light to analyze the surrounding environment. This makes them very versatile. Biological and mechanical devices emit heat, making them visible even in darkness. These cameras are highly accurate and require only a small amount of heat to operate effectively.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 24px; font-family: Arial;"><strong>How does thermal imaging work?</strong></span></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 22px; font-family: Arial;">Visible light is extremely useful to humans and other living organisms, but it represents only a small portion of the electromagnetic spectrum. Infrared radiation, generated by heat, occupies a much larger "space" in the spectrum. Infrared thermal imagers capture and assess the interactions of heat that is absorbed, reflected, and sometimes even propagated.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 22px; font-family: Arial;">The level of thermal radiation emitted by an object is called its thermal signal. The hotter a given object is, the more it will radiate into the environment. Thermal imagers can distinguish between heat sources and small differences in thermal radiation. They compile this data into a complete "thermal map," distinguishing them by heat level.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 24px; font-family: Arial;"><strong>What are the uses of thermal imaging?</strong></span></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 22px; font-family: Arial;">Thermal imagers have been used since the Korean War, initially for nighttime reconnaissance and combat. Since then, they have been improved for use by firefighters, electricians, law enforcement officers, and rescue teams in disaster areas. They are also widely used for building inspection, maintenance, and optimization.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 24px; font-family: Arial;"><strong>How can thermal imaging be achieved?</strong></span></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 22px; font-family: Arial;">Thermal imaging can be a compact and effective technique. Simple thermal imagers assess heat sources centered on a pair of crosshairs. More sophisticated systems offer multiple comparison points, allowing users to analyze environmental conditions. The color palette of cameras varies greatly, from monochrome to a full "rainbow" palette.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 24px; font-family: Arial;"><strong>What should you be looking for in a thermal imaging device?</strong></span></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 22px; font-family: Arial;">To be precise, your needs for a thermal imager depend on the environment in which it will be used. However, there are two key quality-differentiating factors for thermal imagers: detector resolution and thermal sensitivity.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 22px; font-family: Arial;">Like many other displays, resolution describes the total number of pixels – for example, a 160x120 display consists of 19,200 pixels. Each pixel has associated thermal data, so a larger display can produce a sharper image.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 22px; font-family: Arial;">Thermal sensitivity is the threshold of difference that an imager can detect. For example, if a device has a sensitivity of 0.01°, it can distinguish objects with a temperature difference of one percent. The minimum and maximum temperature ranges are also important.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-align: justify; line-height: 1.5;"><span style="color: rgb(245, 245, 245); font-size: 22px; font-family: Arial;">Thermal imagers have some fundamental limitations: for example, they cannot see through glass due to the reflective properties of materials. They can also see but not penetrate walls. Nevertheless, thermal imaging has proven useful in many applications.</span></p><p style="text-align: justify; line-height: 1.5;"><br></p><p style="text-indent: 21pt; text-align: center;"><img src="https://www.mhnvnightvision.com/uploads/file-1764820182709-976432515.png" alt="MHNV® | What is an infrared thermal imager?

However, this does not mean that all infrared thermal imagers can meet the requirements of temperature measurement. The requirements for infrared thermal imagers will vary depending on different environmental factors and the target being measured. So, what are the algorithms for the field of view and minimum resolution of infrared thermal imagers? MHNV will provide a detailed explanation below !</span></p><p><br></p><p><span style="color: rgb(245, 245, 245); font-size: 19px; font-family: &quot;Arial Bold Italic&quot;;"><em><strong> Spatial resolution definition</strong></em></span></p><p><span style="color: rgb(245, 245, 245); font-size: 16px; font-family: &quot;Arial Regular&quot;;">Spatial resolution refers to the minimum distance between two adjacent targets that an infrared thermal imager can identify. It can also be considered as the side length of a pixel on the thermal imager's detector, magnified by the optical lens, representing an angular density in actual space—that is, the spatial density of thermal detection. Because the lens provides optical magnification, the unit of spatial resolution is radians; given a fixed infrared thermal imager detector, spatial resolution depends only on the lens.</span></p><p><span style="color: rgb(245, 245, 245); font-size: 16px; font-family: &quot;Arial Regular&quot;;">1. It is usually expressed in milliradians (mrad) as the field of view (IFOV) of an instantaneous thermal imager. This represents the smallest angular resolution unit of the thermal imager. That is, one temperature point on the thermal imager represents the side length of a square area in actual space.</span></p><p><span style="color: rgb(245, 245, 245); font-size: 16px; font-family: &quot;Arial Regular&quot;;">2. This determines the sharpness of the image from the infrared thermal imager and is the smallest size that the thermal imager can measure. It is related to the optical image quality, the focal length of the optical convergence system, and the linear dimensions of the infrared sensor.</span></p><p><br></p><p><span style="color: rgb(245, 245, 245); font-size: 19px; font-family: &quot;Arial Regular&quot;;"> </span><span style="color: rgb(245, 245, 245); font-size: 19px; font-family: &quot;Arial Bold Italic&quot;;"><em><strong>Spatial resolution algorithm:</strong></em></span></p><p><span style="color: rgb(245, 245, 245); font-size: 16px; font-family: &quot;Arial Regular&quot;;">Spatial resolution</span></p><p><span style="color: rgb(245, 245, 245); font-size: 16px; font-family: &quot;Arial Regular&quot;;">=Pixel Size (Array Pitch) / Lens focal length.

At the heart of every NVD lies the image intensifier tube—the critical component that converts faint light into a visible image. But like any precision technology, these tubes have a finite lifespan, and understanding the factors that influence their durability is key to maximizing your investment.</span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">As a leading manufacturer of night vision and thermal imaging equipment, MHNV has engineered industry-trusted devices like the MH-PVS14 Monocular, PVS31 Binocular, and MH-PVS7 Binocular-Monocular with advanced designs to protect image intensifier tubes and extend operational life. Below, we break down the core factors affecting tube lifespan and how MHNV’s products address these challenges.</span></p><p style="text-align: center;"><img src="https://www.mhnvnightvision.com/uploads/file-1764139517930-319211812.jpg" alt="MHNV® | What Factors Affect the Lifespan of Image Intensifier Tubes in Night Vision Devices?" data-href="https://www.mhnvnightvision.com/uploads/file-1764139517930-319211812.jpg" width="" height="" style="width: 495.99px;height: 495.99px;"></p><p><span style="color: rgb(225, 60, 57); font-size: 19px; font-family: Arial;"><strong>1. Operational Usage: Frequency, Duration, and Environment</strong></span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">The most direct factor impacting an image intensifier tube’s lifespan is how and where you use it.</span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Usage Frequency &amp; Duration: Image intensifier tubes are rated for a specific number of operational hours (typically 10,000–20,000 hours for Gen 3 tubes). Continuous, prolonged use will naturally wear down the tube’s photocathode and microchannel plate (MCP)—the components responsible for amplifying light. For example, a security team using an NVD 8 hours daily will consume lifespan faster than a hunter who uses it occasionally on weekends.</span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Environmental Conditions: Extreme temperatures, humidity, dust, and shock can severely damage the tube. MHNV’s products are built to withstand harsh environments: the MH-PVS14 features a rugged, waterproof housing (IPX67-rated) to resist moisture and dust, while the PVS31 Binocular’s shock-absorbent design protects the tube from impacts during tactical operations. Whether you’re in freezing mountain terrain or humid jungle conditions, our devices shield the intensifier tube from environmental stressors.</span></p><p style="text-align: center;"><img src="https://www.mhnvnightvision.com/uploads/file-1764139559913-569692646.jpg" alt="MHNV® | What Factors Affect the Lifespan of Image Intensifier Tubes in Night Vision Devices?" data-href="https://www.mhnvnightvision.com/uploads/file-1764139559913-569692646.jpg" width="" height="" style="width: 501.91px;height: 501.91px;"></p><p style="text-align: left;"><span style="color: rgb(225, 60, 57); font-size: 19px; font-family: Arial;"><strong>2. Light Exposure: Avoid Overexposure to Bright Light</strong></span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Image intensifier tubes are designed for low-light environments—direct exposure to bright light (e.g., sunlight, vehicle headlights, flashlights) is one of the fastest ways to shorten their lifespan.</span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Bright light overwhelms the tube’s photocathode, causing "blooming" (a whiteout effect) and permanent damage to the MCP. While most NVDs include automatic brightness control (ABC) to mitigate this, improper use (e.g., leaving the device on in daylight) can still harm the tube.</span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">MHNV takes light protection a step further: the MH-PVS7 Binocular-Monocular integrates a dual-stage ABC system and a manual bright-light cutoff switch, instantly shutting down the tube if exposed to excessive light. This proactive design ensures the intensifier tube is never subjected to damaging brightness, preserving its performance for years.</span></p><p><span style="color: rgb(225, 60, 57); font-size: 19px; font-family: Arial;"><strong>3. Quality of Manufacturing: Components and Craftsmanship</strong></span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Not all image intensifier tubes are created equal—the quality of materials, engineering, and assembly directly impacts lifespan.</span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Tube Grade: Gen 3 tubes (the gold standard for modern NVDs) offer longer lifespans than Gen 2+, thanks to superior photocathode materials and MCP design. </span></p><p style="text-align: center;"><img src="https://www.mhnvnightvision.com/uploads/file-1764139602855-402351160.jpg" alt="MHNV® | What Factors Affect the Lifespan of Image Intensifier Tubes in Night Vision Devices?" data-href="https://www.mhnvnightvision.com/uploads/file-1764139602855-402351160.jpg" width="" height="" style="width: 484.98px;height: 484.98px;"></p><p><span style="color: rgb(225, 60, 57); font-size: 19px; font-family: Arial;"><strong>4. Maintenance and Storage: Proper Care Extends Lifespan</strong></span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Even the most durable image intensifier tubes require basic maintenance to maximize lifespan:</span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Regular Cleaning: Dust, oil, or debris on the objective lens can cause uneven light distribution, forcing the tube to work harder. MHNV provides a specialized cleaning kit with every device to safely remove contaminants without scratching lenses.</span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Proper Storage: Store your NVD in a dry, temperature-controlled environment (15–25°C) when not in use. Avoid storing it with batteries installed, as leakage can corrode internal components near the tube. The MH-PVS14 and MH-PVS7 come with protective carrying cases with foam padding, keeping the device safe during transport and storage.</span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">Professional Servicing: Avoid disassembling the NVD yourself—internal adjustments require specialized tools. MHNV offers factory servicing for all our products, including tube inspections and calibrations, to ensure your device remains in optimal condition.</span></p><p style="text-align: center;"><img src="https://www.mhnvnightvision.com/uploads/file-1764139636843-637725232.jpg" alt="MHNV® | What Factors Affect the Lifespan of Image Intensifier Tubes in Night Vision Devices?" data-href="https://www.mhnvnightvision.com/uploads/file-1764139636843-637725232.jpg" width="" height="" style="width: 497.95px;height: 497.95px;"></p><p><span style="color: rgb(225, 60, 57); font-size: 19px; font-family: Arial;"><strong>Invest in Durability with MHNV’s Night Vision Devices</strong></span></p><p><span style="color: rgb(250, 250, 250); font-size: 19px; font-family: Arial;">The lifespan of an image intensifier tube isn’t just about the tube itself—it’s about how the entire device is engineered to protect it.

They use heat detection: "seeing" infrared radiation to turn invisible risks into clear warnings. Cameras capture this in three steps: lens collects radiation, detector turns heat to signals, processor makes a display (warm objects stand out). No visible light needed—indispensable for low light, fog, rain or snow.</span></p><p style="text-align: justify;"><br></p><p style="text-align: justify;"><img src="https://www.mhnvnightvision.com/uploads/file-1757929349290-39842667.jpg" alt="file-1757929349290-39842667.jpg" data-href="https://www.mhnvnightvision.com/uploads/file-1757929349290-39842667.jpg" width="" height="" style=""></p><p style="text-align: justify;"><br></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px;">Traditional car headlights, reliant on reflected light, are limited to about 150 meters and struggle in adverse weather due to scattering. Thermal cameras, however, detect heat directly, extending their range to over 300 meters and penetrating obscurity. They can identify pedestrians, animals, or disabled vehicles far beyond headlight reach—for example, highlighting a cyclist in shadows or a deer hidden in mist—giving drivers critical extra seconds to react when human vision falls short.</span></p><p style="text-align: justify;"><br></p><p style="text-align: justify;"><img src="https://www.mhnvnightvision.com/uploads/file-1757673504842-466923851.jpg" alt="file-1757673504842-466923851.jpg" data-href="https://www.mhnvnightvision.com/uploads/file-1757673504842-466923851.jpg" width="" height="" style=""></p><p style="text-align: justify;"><br></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px;">At the forefront of this innovation is MHNV, a brand specializing in high-performance thermal imaging solutions for vehicles.

Whether it's for hunting in complex terrains, security patrols in low-light environments, or professional outdoor exploration, different application needs will directly affect the choice of thermal scope performance parameters and functional configurations. Only by targeting your actual needs can you pick a thermal scope that truly meets your expectations.</span></p><p style="text-align: justify;"><br></p><p style="text-align: start;"><img src="https://www.mhnvnightvision.com/uploads/file-1756116276187-669953717.jpg" alt="file-1756116276187-669953717.jpg" data-href="https://www.mhnvnightvision.com/uploads/file-1756116276187-669953717.jpg" width="" height="" style="width: 1027.00px;height: 1036.61px;"></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px; font-family: Arial;"> </span></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px; font-family: Arial;"> </span><span style="color: rgb(255, 255, 255); font-size: 22px; font-family: Arial;"><strong>2. Focus on the Core of Thermal Detectors</strong></span></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px; font-family: Arial;">The thermal detector is the "heart" of a thermal scope, and its performance directly determines the imaging effect and practicality of the device.</span></p><p style="text-align: justify;"><br></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px; font-family: Arial;"><strong>2.1 Resolution</strong></span></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px; font-family: Arial;">Resolution is the primary indicator for evaluating the actual quality of a thermal detector. A higher resolution means that the thermal image presented is clearer and more detailed. Even when observing distant targets, it can avoid the annoying "pixelated" blur, allowing you to clearly capture every subtle feature of the target, which is crucial for accurately identifying targets.</span></p><p style="text-align: justify;"><br></p><p style="text-align: start;"><img src="https://www.mhnvnightvision.com/uploads/file-1756116306885-112767653.jpg" alt="file-1756116306885-112767653.jpg" data-href="https://www.mhnvnightvision.com/uploads/file-1756116306885-112767653.jpg" width="" height="" style="width: 994.00px;height: 1036.41px;"></p><p style="text-align: justify;"><br></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px; font-family: Arial;"><strong>2.2 NETD (Noise Equivalent Temperature Difference)</strong></span></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px; font-family: Arial;">NETD reflects the thermal detector's ability to distinguish the smallest temperature differences of the target. The smaller the NETD value, the more sensitive the detector is. It can capture the tiny temperature changes between the target and the surrounding environment, making the target stand out more clearly in the thermal image, even in complex and confusing backgrounds.</span></p><p style="text-align: justify;"><br></p><p style="text-align: start;"><img src="https://www.mhnvnightvision.com/uploads/file-1756116323336-901252228.jpg" alt="file-1756116323336-901252228.jpg" data-href="https://www.mhnvnightvision.com/uploads/file-1756116323336-901252228.jpg" width="" height="" style="width: 1037.00px;height: 855.86px;"></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px; font-family: Arial;"><strong>2.3 Refresh Rate</strong></span></p><p style="text-align: justify;"><span style="color: rgb(255, 255, 255); font-size: 19px; font-family: Arial;">The refresh rate refers to the number of times the image frame is updated per second, usually expressed in Hertz (Hz) or frames per second (fps). A higher refresh rate ensures that when tracking moving targets, the thermal image is smooth and free of trailing. Whether it's a rapidly moving prey during hunting or a dynamic object in security monitoring, it can be displayed stably and clearly, helping you respond quickly and accurately.</span></p><p style="text-align: justify;"><br></p><p style="text-align: start;"><img src="https://www.mhnvnightvision.com/uploads/file-1756116342728-14742614.jpg" alt="file-1756116342728-14742614.jpg" data-href="https://www.mhnvnightvision.com/uploads/file-1756116342728-14742614.jpg" width="" height="" style="width: 1037.00px;height: 684.41px;"></p><p style="text-align: start;"><br></p><p style="text-align: start;"><br></p><p style="text-align: left; line-height: 1.5;"><span style="color: rgb(255, 255, 255); font-size: 22px; font-family: Arial;"><strong>Engineer Manager Name: Jacky</strong></span></p><p style="text-align: left; line-height: 1.5;"><span style="color: rgb(255, 255, 255); font-size: 22px; font-family: Arial;"><strong>WhatsApp/ Wechat: 0086-187 9245 6795</strong></span></p><p style="text-align: start; line-height: 1.5;"><span style="color: rgb(255, 255, 255); font-size: 22px; font-family: Arial;"><strong>Email: </strong></span><a href="mailto:mh_elec@126.com" target="_blank"><span style="color: rgb(255, 255, 255); font-size: 22px; font-family: Arial;"><strong>mh_elec@126.com</strong></span></a><span style="color: rgb(255, 255, 255); font-size: 22px; font-family: Arial;"><strong> or </strong></span><a href="mailto:jacky@mh-elec.com" target="_blank"><span style="color: rgb(255, 255, 255); font-size: 22px; font-family: Arial;"><strong>jacky@mh-elec.com</strong></span></a></p><p style="text-align: start; line-height: 1.5;"><br></p><p style="text-align: start; line-height: 1.5;"><br></p><p><br></p>
