Thermal Sight Lens Description:
1. Thermal sights are also called infrared aiming lenses, long-wave 8-12um infrared lenses, mainly made of Ge, ZnSe and other optical materials, all of which are manual focus. Stable performance and wide application.
2. Thermal sights mainly have focal lengths of 19mm, 25mm, 35mm, 50mm, 75mm, and 100mm, and apertures of 1.0, 1.1, 1.2, and 1.3, among which focal lengths of 35mm and 50mm are the most widely used. And meet the matching standard of 17um detector.
Factors that determine the quality of the lens:
1, the number of lenses: a variety of lens combinations can reduce color bias, improve focus, but will reduce light transmittance.
2, lens transmittance: lenses with good transmittance are expensive, and poor lenses will block light through.
3. Coating and grinding: lens coating and grinding technology affects the quality of the lens.
4, mechanical device: the accuracy of the internal mechanical structure of the lens affects the accuracy and reliability of the lens movement. Poor mechanical construction can lead to adjustment errors and inconsistencies.

FAQ:
What Are DLC And AR Coating?
Diamond-like carbon (DLC) membrane is an amorphous carbon membrane. The membrane contains a certain number of sp3 bonds, giving it a series of excellent properties close to diamond. It has the advantages of low deposition temperature and large area deposition.
Among various hard membranes, DLC membrane can be positioned as a membrane material with high hardness and excellent wear resistance and low coefficient of friction.
AR (Anti-Reflection) membrane cannot change the absorption rate of the lens itself. It can only increase the transmittance by reducing the reflectance on both sides of the lens, which is the so-called "reflection and antireflection".
Light is an electromagnetic wave. By matching the refractive index and thickness of the AR membrane, the light produces multi-beam interference in the AR membrane-destructive interference on the upper surface and constructive interference on the lower surface.
