Infrared Manual Focus Lens Description:
Focal Length 50mm F0.8 Infrared Manual Focus Lens Germanium Lens For 1024x768-17um Detector.
8-12um Long Wave Germanium Lens For Infrared Sights, Infrared Camera, Thermal Imager, Monitor Camera, etc.
Different Types of Lenses:
Lenses can be categorized based on their focal length, numerical value of focal length, aperture, and telescopic adjustment.
1. Focal length determines the type of lens, such as fixed, telescopic, automatic or manual iris, and more.
2. The size of the focal length determines the lens type, including standard, wide-angle, telephoto, and others.
3. The lens telescopic adjustment method includes electric and manual telescopic lenses, among others.

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.
