optical lens

The design of zinc selenide (ZnSe) planar convex (PCX) lenses is used for focusing or collimating applications in medium and long wavelength infrared spectroscopy. These lenses are made of II-VI infrared zinc selenide material, with a volume absorption coefficient of<0.0005cm-1 at a wavelength of 10.6 µ m, and can provide uncoated or various broadband antireflective coating options. The 8-12 µ m coating is very suitable for use with CO2 lasers and thermal camera applications, while the dual band 3-12 µ m coating is suitable for hyperspectral applications.

The irregularity of zinc selenide flat convex lens at 10.6 µ m wavelength is< λ/ 20, with a surface quality of 40-20 and a surface roughness of<50 Å. Three diameter options are available, with an effective focal length range from 12.7mm to 200mm.

Attention: Special care should be taken when taking zinc selenide, as it is a toxic substance. Rubber or plastic gloves should be worn throughout the entire operation process to avoid contact..
