Product Description

Application of infrared lens:

With the rapid development of infrared optical technology, infrared lens is more and more used in civil, industrial, military and other fields.

Because the temperature change will affect the surface shape of the optical component of the infrared lens, the refractive index of the optical component, the focal shift of the lens, etc., resulting in poor imaging quality and blurred lens. Image and contrast reduction.

Therefore, non-thermal design is one of the essential links in the design process of infrared lens.
