Double-Convex (DCX) Lenses, D=25.40mm, F=100.00mm, Uncoated CVD Laser Grade ZnSe(ZnSe), model 110158, is manufactured by United Optical Technology Co., Ltd.
Zinc Selenide (ZnSe) Double Convex Lenses are double convex lenses based on zinc selenide.
Zinc selenide is a commonly used optical glass material in the infrared band. The transmission band is 600nm-16μm. It has the characteristics of low absorption and thermal shock resistance. It is often used in thermal imaging systems, and can also be used in some visible light optical systems, and can be used as the substrate for a variety of optical elements. Special attention should be paid to the fact that zinc selenide is a toxic material. Please be sure to wear gloves when using it and wash your hands after use.

A lenticular lens focuses light into a point with a positive focal length and consists of two convex surfaces of equal radius. Commonly used in imaging relay systems and object imaging at limited conjugate distances. The characteristic is that the greater the conjugation ratio, the greater the aberration produced.
