In the optical system, when the light passes through the lens surface, it occurs refraction as well as reflection. The reflection will cause the loss of light energy and the reflected ghost image and stray light will lead to a poor imaging quality.

When the observation distance is 5 kilometers, what type of Infrared Security Lenses should I choose? What’s the difference between a fixed focus motorized lens and a continuous zoom lens?

As an important factor determining the performance of thermal imaging infrared materials greatly affect the development of infrared technology. High-performance infrared materials can better speed up the development and application of thermal imaging lenses in various fields.

With the development of thermal imaging technology, it has been more and more widely applied in diverse fields.

Chalcogenide glass is the most popular material for mass production of infrared lenses. Because it has stable refractive index, abundant resources, high transmittance at wide infrared waveband and it is suitable for mass molding production which is cost-effective.

Due to the small dimension and strict cost requirement, conventional processing technique is incapable of mass production. To solve this problem, Sunny Infrared Optics was devoted to the SWLO (the small wafer-level optical processing technology) development.
