FL25/90mm F1.0/1.2 Uncooled Dual-FOV LWIR Lens For 640x512-17um

Feature of Uncooled Dual-FOV LWIR Lens:

The long-wave double-field infrared optical lens can be equipped with a front fixed group with positive refractive power along the light from the object direction to the incident direction, which is a meniscus germanium positive lens with a convex surface facing the object side; a zoom with negative refractive power The group is a double-concave germanium negative lens for switching the field of view; the rear fixed group with positive refractive power is composed of a double-convex germanium positive lens and a meniscus germanium positive lens with a convex surface facing the object side. The optical system has good imaging quality in two fields of view of 25/90mm, and can realize fast switching of focal length.

Infrared technology can be applied to the detection of targets at night and under adverse weather conditions such as smoke, fog and dust, so as to realize all-weather observation. The single-field lens can only meet one function of detection or identification, and it needs to be equipped with two lenses, and it is very cumbersome to replace the lens. The dual-field infrared optical lens has two fields of view, wide and narrow, which can meet the functions of detection and identification respectively. The wide field of view is used for target detection and the narrow field of view is used for target identification.
