Infrared Athermal Lens Description:
1. Focal Length 19mm F1.0 Infrared Athermal Lens For 640x512-12um Detector.
2. 8-12um Long Wave Infrared Athermal Lens For Infrared Sights, Infrared Camera, Monitor, etc.
3. Fixed focal length, suitable for working scenes where focusing is difficult.
Background on Infrared Lenses Technology:
Apart from being high-resolution, compact, and lightweight, infrared lenses in civilian applications need to be cost-effective and capable of functioning in various high and low-temperature settings.
Currently, most infrared optical athermalization lenses in the market use an optical structure of three or more elements to achieve athermalization. However, the scarcity of materials such as single crystal germanium and zinc selenide results in high prices and density, leading to hefty and expensive lenses.

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.
