📝 Thermal Imager (InfiRay) iRay Finder FL25R with Rangefinder (384×288) 1300 m
Thermal Imager (InfiRay) iRay Finder FL25R with Rangefinder (384×288) 1300 m is a compact thermal monocular with an integrated laser rangefinder, a 384×288 sensor and 12 µm pixel pitch, designed for stable detection of thermal targets at distances up to 1300 meters. The fast F/1.0 objective lens with a diameter of 25 mm ensures efficient image formation even under low thermal contrast and in challenging weather conditions.
The model is equipped with a 1280×960 LCOS display, a Wi-Fi module for video transmission, and a 50 Hz refresh rate, ensuring smooth rendering of moving objects. The built-in аккумулятор provides up to 6 hours of автономous operation, while the IP66 protection rating allows reliable use in rain, fog, or dusty environments without loss of functionality.
🫡 We are a team of veterans
We are a team of veterans who use thermal imaging devices during night observation, patrol operations, and terrain control. We evaluate equipment based on its real-world field effectiveness, where stability, rapid target detection, and comfort during prolonged use are critical factors.
The FL25R model demonstrated reliable performance during night monitoring and detection of thermal targets at medium distances. The integrated laser rangefinder significantly increases the accuracy of distance estimation to a target, which is crucial for reconnaissance and tactical observation tasks.
