Thermal Sight Lens Description:
Focal Length 50mm F1.2 Infrared Germanium Lens Thermal Sight Lens For 640x512-17um Detector.
8-12um Long Wave Infrared Lens, IR Aiming Lens Apply to Infrared Sights Scope, Infrared Camera, Monitor Camera, Thermal Imager, Thermal Sight Scope, Drone Monitor, etc.
Infrared multi-layer coating technology (IR Coating), infrared anti-reflection:
The multi-layer composite coating technology can reduce light scattering loss, increase the light transmittance of the lens, and make the picture clearer.
At the same time, the anti-reflection of light waves with a wavelength of 750-1000nm is improved.
The surface of the lens is generally dark green.
Infrared multi-layer coating technology (IR Coating) can improve the near-infrared light transmittance, and can play a icing on the cake effect for the infrared lens to better achieve high-definition.

FAQ:
What Are DLC And AR Coating?
Diamond-like carbon (DLC) membrane is an amorphous carbon membrane. The membrane contains a certain number of sp3 bonds, giving it a series of excellent properties close to diamond. It has the advantages of low deposition temperature and large area deposition.
Among various hard membranes, DLC membrane can be positioned as a membrane material with high hardness and excellent wear resistance and low coefficient of friction.
AR (Anti-Reflection) membrane cannot change the absorption rate of the lens itself. It can only increase the transmittance by reducing the reflectance on both sides of the lens, which is the so-called "reflection and antireflection".
Light is an electromagnetic wave. By matching the refractive index and thickness of the AR membrane, the light produces multi-beam interference in the AR membrane-destructive interference on the upper surface and constructive interference on the lower surface.
