Lwir Athermal Lens Product Description
Wavelength: 8-12um Long Wave
Shape: Aspheric
Usage: Infrared Option
Package: First with the desiccant into the bubble bag, and then with plastic box packaging, and finally cartons.
Application of Infrared Lens:
With the rapid development of infrared optical technology, infrared lenses are increasingly used in civil, industrial, military and other fields.
Because the change of temperature will affect the surface shape of the optical element of the infrared lens, the refractive index of the optical element, the focal shift of the lens, etc., resulting in the deterioration of the imaging quality of the lens, blurred image and decreased contrast.
Therefore, athermalization design is one of the essential links in the design process of infrared lens.

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.
