Characteristics of infrared lens germanium material:

Germanium lenses are highly regarded for their unique qualities in the realm of infrared cameras. Among all the options available, germanium glass is the preferred choice due to its exceptional refractive index.

Unlike regular optical glass, germanium glass exclusively permits the transmission of infrared light, making it perfect for capturing images in low light settings.

This distinctive characteristic allows for the detection of concealed animals and plants that would otherwise remain unnoticed by the human eye.

However, germanium is a scarce element with limited availability, resulting in costly extraction and lens manufacturing processes.

Consequently, infrared camera lenses tend to be pricier compared to standard lenses made from artificial 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.
