Supplier
Umoptics
Part Number
PZS05-
Category
Optical Lenses
Origin
China

The characteristic of zinc sulfide biconvex lenses is that the focal length of the middle part of the lens surface is longer, and the focal length of the end part of the lens surface is shorter. Made of zinc sulfide material, it has excellent optical and mechanical properties. Zinc sulfide biconvex lenses are used to concentrate light from point sources or transmit images to other optical systems. It has a high optical transmittance and good optical properties in multiple spectral bands. UM OPTICS provides a diameter of 2-300mm and a thickness of 0.12-60mm (with an accuracy of 20-10,1)/ 10L@633nm ）The zinc sulfide biconvex lens can be coated with MgF2, UV-AR, UV-VIS, VIS-EXT, VIS-NIR, NIR I, NIR II, Telecom NIR, SWIR, SWIR, YAG-BBAR and other film systems.
