Infrared Athermal Lens Description:
Focal Length 19mm F1.2 Infrared Germanium Lens, Long Wave Infrared Athermal Lens For 640x512-12um Detector.
Fixed focal length, suitable for Infrared Sights, Infrared Camera, Car Monitor, Drone Monitor, etc.
By using this athermalized lens, we can get very clear and accurate thermal imaging effect. These imaging effects can be widely used in many fields such as industrial production, safety monitoring, and medical care.
Infrared lenses are usually made of germanium glass. This glass has a high refractive index. It is only transparent to infrared light, but opaque to visible and ultraviolet light, so it can distinguish between animals and plants in very dark environments.
The lens of an ordinary camera is made of optical glass, and its main function is to refract light, or enlarge objects. Generally, optical glass is synthetic.
Compared with the common germanium dispersed metal element used in ordinary camera lenses, the reserves of infrared thermal camera lenses are relatively high in nature, but it is very difficult to extract high concentration germanium, so the production cost of germanium lenses is relatively high. The price is often higher than that of ordinary camera lenses.
