Infrared Athermal Lens Description:
1. Focal Length 6.9mm F1.0 Infrared Germanium Lens For 640x512-17um Detector.
2. 8-12um Long Wave Athermal Lens For Infrared Sight Scope, Infrared Camera, Car Monitor, Drone Monitor.
3. Fixed Focal Focal Length, Commonly used materials are Ge, ZnS, ZnSe, Si, Chalcogenide, etc
Main features of germanium lenses:
Germanium glass is the first choice for infrared camera lenses because of its high refractive index.
Unlike regular optical glass, it only allows infrared light through, making it ideal for capturing images in dim light.
This unique property makes it possible to identify invisible animals and plants that cannot be seen with the naked eye.
However, germanium is a scarce element with limited availability, resulting in an expensive extraction and production process for these lenses.
Therefore, infrared camera lenses usually have a higher price compared to standard camera lenses made of man-made materials.

FAQ:
What is an anti-reflection film?
Anti-Reflective Coating (AR) is a surface optical coating that improves transmittance by reducing light reflection. In complex optical systems, it can improve contrast by reducing the 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 it acts on. When the light is reflected twice on the anti-reflection film, it interferes with the original reflected light, thus weakening the reflected light. According to the law of conservation of energy, the energy of light does not change. Thus, when the reflected light decreases, the transmitted light increases. This is the principle of AR coating. In general, when selecting an anti-reflection film, it is necessary to determine the wavelength, such as infrared, visible light and ultraviolet light.
