Long Wave Athermal Lens Description
8-12um Long Wave Wavelength
Aspheric Lens
Fixed Focal Focus
AR Coating Available
Infrared Lens Background Technology：
In the civilian field, in addition to high resolution, small size and light weight, infrared lenses are also required to be low in cost and able to maintain working performance in different high and low temperature environments.
However, most infrared optical athermalization lenses currently on the market generally adopt an optical structure of 3 or more elements.
To achieve optical athermalization. Due to the scarcity of materials such as single crystal germanium and zinc selenide, the price is high, and the density is high, resulting in heavy weight and high cost of the optical lens.
