Infrared Athermal Lens Description:
1. Focal Length 24mm F1.0 Infrared Germanium Lens For 640x512-12um Detector.
2. 8-12 Long Wave Athermal Lens For Infrared Sights, Infrared Camera, Car Monitor, Drone Monitor, etc.
3. Support OEM, ODM Service.
The germanium lens is known for its distinct features:
When it comes to infrared camera lenses, germanium glass is the top choice due to its exceptional refractive index.
Unlike regular optical glass, it is solely transparent to infrared light, which makes it perfect for capturing images in low-light settings.
This exceptional characteristic enables the detection of animals and plants that are otherwise unseen by the naked eye.
However, germanium is a rare element that is only found in limited amounts, which makes extracting and producing lenses expensive.
Therefore, the cost of infrared camera lenses is typically higher than standard camera lenses made of artificial materials.

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.
