Infrared Athermal Lens Description:
Focal Length 11mm F1.2 Infrared Athermal Lens Germanium Lens For 640x512-12um Detector.
8-12um Long Wave Germanium Thermal Lens For Drone Monitor, Infrared Sights, etc.
Features of infrared lens:
1) Night vision in low light conditions: When it comes to seeing in the dark, the light we receive from the atmosphere is mainly concentrated in the short-wave infrared band range of 1.0-1.8um. This makes long-wave infrared night vision imaging more efficient than using visible light. It has some great advantages, such as capturing detail even in deep shadows and being able to see through window panes. This makes it ideal for use in dark places or at night.
2) Simple optical setup: Long wave infrared light can easily pass through the glass, so long wave infrared cameras do not need a special housing. It requires only one piece of protective window glass, which gives it great flexibility when used on a specific platform or occasion.

FAQ:
What Is An AR Coating?
Anti-reflective coating (English: Anti-reflective coating, AR) is a surface optical coating that increases transmittance by reducing light reflection. In complex optical systems, it can improve contrast by reducing scattered light in the system.
Many coatings include transparent film structures with different refractive indices. The thickness of the film determines the wavelength of the reflected light that it acts on. When light is reflected twice on the AR coating, it will interfere with the original reflected light, thereby weakening the reflected light. According to the conservation of energy, the energy of light does not change. Therefore, when the reflected light decreases, the transmitted light increases. This is the principle of AR coating. Generally, when choosing an AR coating, you need to determine the wavelength, such as infrared, visible and ultraviolet.
