Infrared Athermal Lens Description:
Material: Germanium, Chalcogenide, Zinc Selenide, Zinc Sulfide, Silicon, Calcium Fluoride, Barium Fluoride, etc.
Focal Length 25mm F1.0 Long Wave Infrared Germanium Lens Athermal Lens For 640x512-12um Detector.
8-12um Long Wave Athermal Lens Apply to Infrared Sights, Drone Monitor, Car Monitor, etc.
The temperature coefficient of refractive index of infrared materials is 1 to 2 orders of magnitude larger than that of visible light glass.
In the field of high-precision detection and early warning, infrared systems are required to work in the temperature range of -40°C~+60°C, so changes in ambient temperature have a great impact on The performance of the infrared system is greatly affected.
