Product Description

Dia250mm/10" 425-675nm AR Coated Optical Achromatic Doublets Customize Focal Length for Telescope/Binocular/Microscope

 

GPG glass lenses are made from either the highest grade of BK7 optical glass or fused silica. The fused silica lenses are ultra-violet quality synthetic fused silica. They are best for applications that require either the superior UV or IR transmission, or the improved hardness of silica. We have a vast range of different diameters from 2.5mm to 1000mm and focal lengths from 8.0mm to 5000mm.
