Infrared Athermal Lens Description:
Focal Length 20mm F1.0 Infrared Germanium Lens For 640x512-17um Detector.
8-12um Long Wave Infrared Athermal Lens For Drone Monitor.
Application Range of Infrared Lens:
The range of application of infrared lens is very wide, it can be used not only for special purposes corresponding to infrared, but also as ordinary lens.
In other words, according to different usage occasions, the corresponding infrared lens can be used flexibly with conventional color cameras, black and white cameras, and day and night conversion cameras.
Black-and-white cameras do not have infrared cut filters, but the spectrum of sunlight also contains infrared light, so even under daylight conditions, the imaging of black-and-white cameras will be interfered by infrared rays. Therefore, with the corresponding infrared lens can effectively improve the imaging quality.

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.
