Clip-On Infrared Thermal Imager Scope
Clip-On Infrared Thermal Imager Scope – High-Performance Thermal Imaging Attachment for Extended Observation
MHNV® Clip-On Infrared Thermal Imager Scope is a professional grade, long range detection and rapid mounting flexibility. The system uses an uncooled 640×512px vanadium oxide detector with 12μm pixel pitch, achieving vehicle detection at 2,700m and personnel detection at 2,200m. The 25mm F1.0 objective lens gives a wide 17.5°14° field of view and the 1024768 OLED display delivers outstanding clarity in all settings. The device is powered by a normal 18650 lithium battery and allows 7 hours of continuous operation. Compact thermal attachment ≤170x80x70mm is impact resistant to 1,200G and operates from -40degC to +55degC Attaches easily to regular Picatinny rails without tools.

Advanced Thermal Detection Core
At the heart of our system is an uncooled vanadium oxide focal plane array working in the 8-14$\mu$m infrared spectrum. The resolution of the detector is 640×512 pixels, with a pixel pitch of 12μm. The MRTD is 550mK, that provides dependable thermal contrast under bad air circumstances.
With this sensor architecture, the product can track vehicles beyond 2,700 meters and identify them at 750 meters. The personnel detection distance is 2200 meters and the recognition distance is 550 meters, which is appropriate for large-area observation duties and has early target recognition.
Optical Configuration and Field Performance
High-Performance Objective Assembly
The 25mm F1.0 fast objective lens maximizes light-gathering capability within the long-wave infrared spectrum. This large-aperture design sustains image clarity in low-temperature environments where slower optics lose contrast.
Combined with a 17.5°×14° native field of view, operators can conduct broad-area scanning before switching to electronic magnification for detailed inspection. Minimum focus distance begins at 10 meters, accommodating close-range observation scenarios.
Eyepiece and Display System
A 14X magnification eyepiece paired with ±3D diopter adjustment accommodates a wide range of operators. The 45mm exit pupil distance ensures comfortable extended viewing sessions, reducing operator fatigue during prolonged surveillance operations.
The 1024×768 OLED display provides high-contrast imagery across four selectable modes: white heat, black heat, red heat, and metal. These polarity options allow users to optimize target contrast against varying backgrounds and environmental conditions.
Electronic Zoom and Image Processing
The integrated 4-step electronic zoom system offers 1x, 2x, 4x, and 8x magnification levels. This range bridges the gap between wide-area scanning and close target identification without requiring device changes.
Four-style cross cursor division assists with rapid target acquisition and reference marking during extended observation sessions. Operators can switch between modes and magnification levels quickly, maintaining situational awareness across dynamic scenarios.

Clip-On Design and Mounting Flexibility
Instant Picatinny Rail Attachment
The Clip-On Infrared Thermal Imager Scope features a standard Picatinny rail interface that attaches directly to existing optical devices without tools. This design allows you to convert daytime optics into a full thermal observation system in seconds, eliminating the need for re-zeroing or alignment procedures.
The compact ≤170×80×70mm form factor adds minimal size and weight to your existing setup, maintaining balance and handling characteristics.
Optional Helmet Mounting Configuration
Beyond rail mounting, MHNV® offers an optional helmet bracket that enables hands-free observation. This configuration expands deployment flexibility across different operational roles and observation scenarios where handheld operation is preferred.
Power System and Field Logistics
It is powered by a common standard 18650 lithium battery, enabling 7 hours of continuous operation. This standard battery format makes field logistics easier and lowers the cost of spare power sources.
PAL analogue video out functionality to link to external recording equipment or remote displays when documentation or team coordination is required.
Ruggedized Construction and Environmental Protection
It is designed to survive tough field conditions and is rated at 1200G impact resistance. The rugged design ensures optical alignment and electronic stability in extreme stress conditions.
The working temperature range of -40C to +55C enables reliable performance in harsh climates from arctic to desert. Over the entire operational envelope, internal parts are secured from moisture, dust and mechanical stress.
Application Scenarios
Law Enforcement and Tactical Operations
Covert surveillance and target acquisition in urban environments benefit from thermal imaging capability. Where smoke, fog, or high-contrast lighting conditions would degrade traditional observation methods, thermal detection maintains target visibility.
The ability to preserve day-optic alignment ensures rapid response units can transition between observation and engagement without repositioning or recalibration.
Professional Wildlife Management
Wildlife managers conducting population surveys or invasive species control operations can switch from daytime scouting to nocturnal observation without removing their primary optic. This capability is particularly valuable in complex terrain where target precision matters.
Thermal detection cuts through dense foliage and natural camouflage, revealing animal heat signatures that would remain invisible to traditional night vision systems.
Search and Rescue Operations
Dense forest canopy and mountainous terrain present significant challenges for locating missing persons during nocturnal operations. The product enables search teams to detect human heat signatures through thick vegetation and across large areas.
The wide field of view supports rapid area scanning, while electronic zoom enables detailed investigation of potential target locations before committing ground resources.

FAQ
Q: Do I need to re zero with this thermal attachment?
A: No, MHNV® professional clip-on thermal systems are factory-collimated, so the optical path is properly aligned with the zero point of your existing day optic and no field modifications are needed. As part of our quality control process, we evaluate the alignment of the optical axis and simulate a recoil of over 6,000 Joules to ensure that once the device is mounted, your point of aim will be your point of impact.
Q: What maximum day scope magnification can I use with this thermal clip-on?
A: The 640×512 resolution sensor in this device performs well with day scope magnification up to 8x-10x before you start to see the pixel structure in the combined image; after that point, the thermal unit’s own electronic zoom provides you more magnification without pixelation artefacts from the host optic.
Q: How does MRTD affect my performance during humid weather?
A: The device can detect smaller temperature differences between the target and its surroundings thanks to the 550mK MRTD (Minimum Resolvable Temperature Difference), which is particularly important in rainy or humid environments where the thermal contrast is naturally reduced; a lower MRTD value means better target detection capability under adverse atmospheric conditions.
Q: Can this device be used as a handheld thermal monocular?
A: Yes, the compact form factor and ergonomic design allows for quick detachment from rail mounts for handheld scouting applications, providing flexible deployment options where you need to survey an area before attaching the unit to your primary optic or when conducting preliminary reconnaissance away from your main observation position.
Q: Will it work with all day scopes out there?
A: The MHNV® thermal clip-on is designed to be mounted on most optical devices with the standard Picatinny rail mount, provided there is sufficient clearance for the 25mm objective lens diameter and the physical dimensions of your current optic do not block the thermal unit housing; MHNV® provides technical consultation during the selection process to ensure proper compatibility with your specific setup.
