Aspheric Lenses, D=25.40mm, F=25.00mm, Uncoated CVD Laser Grade ZnSe(ZnSe), United Optical Technology Co., Ltd (CAT#: STEM-OP-1349-YJL)

Aspheric Lenses, D=25.40mm, F=25.00mm, Uncoated CVD Laser Grade ZnSe(ZnSe), model 140001, is manufactured by United Optical Technology Co., Ltd.
Zinc Selenide (ZnSe) Aspheric Lenses are aspheric 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.
Note: 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.

Aspheric lenses can better correct spherical aberration. Their surfaces are designed with aspherical aberration. Aspheric lenses are often used to collimate the output light of optical fibers and can be used in barcode scanning, laser collimation, optical imaging and other fields. Aspheric lenses adopt a single element design, which can minimize the number of lenses in a multi-lens optical system.
