Infrared Athermal Lens Description:
Athermal Lens, Fixed Focal Length With DLC Coating.
Focal Length 75mm F1.2 LWIR Athermal Lens For Infrared Sight Scope, Car Monitor, Drone Monitor, etc.
Infrared lens technology Background:
In addition to being high-resolution, compact and lightweight, civilian infrared lenses need to be cost-effective and able to operate in a variety of high and low temperature environments.
At present, most of the infrared optical non-thermal lenses on the market use three or more pieces of optical structure to achieve non-thermal. However, the scarcity of materials such as monocrystal germanium and zinc selenide leads to higher prices and densities, resulting in bulky and expensive lenses.
