Infrared Athermal Lens Description:
Focal Length 100mm F1.2 Infrared Athermal Lens For 640x512-17um Detector.
8-12um Long Wave IR Germanium Lens, Thermal Lens For Infrared Sights, UAV Monitor, Car Monitor.
Feature of the main material germanium lens:
Germanium lens is the preferred material for infrared camera lenses due to its high refractive index.
Unlike regular optical glass, it is only transparent to infrared light, making it ideal for capturing images in low-light conditions.
This unique property allows for the detection of animals and plants that are otherwise invisible to the naked eye.
However, germanium is a rare element found in limited quantities, making it expensive to extract and produce lenses.
So, the cost of infrared camera lenses is often higher than standard camera lenses made of synthetic materials.

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.
