MX 11769 Tube

MX 11769 Tube: High-Performance Gen 3 Image Intensifier with Manual Gain Control for Professional Night Vision Systems

The MX 11769 Tube represents a professional-grade 18mm Generation 3 image intensifier engineered by Xi'an MH Electronics And Technology Co., Ltd. (MHNV®) for demanding low-light environments. Built on a Gallium Arsenide (GaAs) photocathode platform, this tube delivers Figure of Merit (FOM) ratings from 1600 to 2400+, paired with 64–72 lp/mm resolution and Signal-to-Noise Ratio (SNR) of 22–32+. Its defining feature is the external pigtail wire that enables real-time manual gain adjustment, allowing you to fine-tune luminance from near-zero to over 10,000 fL/fL. MHNV®'s auto-gating power supply protects the photocathode from blooming during sudden light transitions, ensuring consistent performance across urban patrols, maritime search operations, and industrial inspection workflows. With over 12 years of manufacturing expertise and CE, RoHS, ISO9001, and FCC certifications, every product ships with serialized test reports and a one-year warranty.

Precision Engineering Meets Field Reliability

MHNV® integrates the product into inverting fiber-optic configurations optimized for PVS-14 and F5032 housings. Each unit undergoes Class-10,000 cleanroom calibration, with rigorous testing for halo (≤0.7 mm typical), Equivalent Background Illumination (EBI ≤0.25), and vacuum stability.

Our vertical manufacturing chain covers optical design, FPGA-based image processing, and mechanical assembly under one roof. This end-to-end control reduces lead times to 3–7 days for stock units and 15–30 days for bulk orders, while ensuring traceable quality from photocathode deposition to final packaging.

Technical Specifications

Four Core Advantages for Mission-Critical Applications

1. Next-Generation Clarity and Durability

The 18mm Gen 3 architecture combines a thin-filmed ion barrier with a multi-alkali photocathode, delivering exceptional image contrast and mechanical robustness. You get superior performance in overcast starlight conditions, where legacy Gen 2 systems struggle with grain and noise.

2. Smart Light Adaptation

Auto-gated models use high-speed switching circuits to respond within milliseconds to flashlights, vehicle headlamps, and muzzle flashes. This prevents image washout and extends tube lifespan by protecting the microchannel plate from saturation.

3. User-Adjustable Brightness

The external pigtail lets you dial down gain during prolonged observation, reducing eye fatigue and preserving night-adapted vision. This feature is invaluable during multi-hour surveillance or maritime patrols, where ambient light fluctuates constantly.

4. Extensive Configuration Options

Choose between white phosphor (P45) for natural color rendering and depth perception, or green phosphor (P43) for traditional contrast. FOM tiers range from 1600 for cost-sensitive projects to 2400+ for extreme low-light requirements, ensuring you pay only for the performance your application demands.

Proven Applications Across High-Stakes Scenarios

Specialized Reconnaissance Operations

Integrated into PVS-14 monoculars, the MX 11769 Tube transitions seamlessly from pitch-black interiors to street-lit urban zones. Manual gain control prevents blooming when passing under streetlights, maintaining situational awareness without helmet removal.

Law Enforcement Tactical Entry

SWAT units rely on auto-gating to counter flashlights and emergency strobes during building clearance. The tube's EBI specification ensures clean imagery even when temperatures rise inside enclosed tactical vehicles.

Maritime Search and Rescue

Deck-mounted systems equipped with high-FOM MX 11769 variants distinguish small reflective surfaces and thermal signatures on water under moonless skies, where Gen 2 systems fail to deliver sufficient contrast.

Industrial Inspection and Wildlife Monitoring

Maintenance crews use white-phosphor models for cable inspection in unlit substations, while conservation teams leverage the tube's spectral response (450–900+ nm) to observe nocturnal species without infrared illumination.

Quality Assurance Rooted in MIL-SPEC Standards

Every product follows MIL-PRF-49427 protocols, including three-zone spot mapping to verify that any internal black spots remain within acceptable diameter limits (measured in mils). MHNV®'s testing suite includes:

• Signal-to-Noise Ratio (SNR) verification via photo-current measurements
• Halo testing to confirm rings around bright sources stay below 1.0 mm
• EBI checks at elevated temperatures to ensure image clarity
• Gain range validation confirming the pigtail's linear response across the full adjustment spectrum

Burn-in testing guarantees vacuum stability and prevents premature photocathode degradation. Each shipment includes a serialized data sheet, CE/RoHS certificates, and MSDS documentation for lithium battery accessories.

FAQ

Q: Can a product be converted to an MX 10160 format?

A: Yes, if you remove the external pigtail and connect a fixed resistor across the gain-control pins you get a non-adjustable tube like the MX 10160, however you lose the ability to manually change brightness and may void your warranty unless done by authorised personnel.

Q: What is causing flickering in an auto-gated product?

A: Flickering is normal behaviour in bright conditions as the high speed power supply is cycling to protect the photocathode from saturation. If the flickering occurs in total darkness, then the power supply circuitry or MCP voltage regulator needs to be replaced under warranty.

Q: What's the difference between P45 White Phosphor and P43 Green in a product?

A: P45 White Phosphor is easier on the eye and provides better depth perception as it provides greyscale imagery closer to natural daylight. It's ideal for search-and-rescue and industrial inspection. P43 Green is still the standard for legacy contracts because of historical familiarity and slightly higher contrast in certain foliage-heavy environments.

Q: What does the Figure of Merit (FOM) mean for this tube?

A: FOM is equal to the resolution (lp/mm) times the SNR. The higher the FOM (e.g. 2400+ vs. 1600) the better the performance in extremely low light situations such as heavily wooded terrain or overcast starlight. This translates directly to your ability to identify targets at farther distances with less ambient illumination.

Q: Is the product sensitive to bright light exposure?

A: Auto-gating provides protection on the millisecond level from transient bright sources (headlights, muzzle flashes). However, long exposures to daylight or direct laser strikes can cause permanent "burn" marks on the photocathode or degraded quantum efficiency. Always use lens caps when storing and transporting to preserve tube lifetime.
