CALCIUM FLUORIDE (CaF2) Plano-concave LENSES
Alkor Technologies - manufacturer of custom Calcium Fluoride plano-concave lenses for Ultraviolet and Infrared applications.
We can make lenses from 3 to 80mm diameter with almost any focal length. We have own growth facility for CaF2 crystal growth. That is why we offer Calcium Fluoride (CaF2) plano-concave lenses at very competitive price - up to 60% lower than major online optical catalogs!
Maximum size of CaF2 plano-concave is 76.2mm diameter. Alkor Technologies manufactures VUV grade CaF2 lenses for 193nm and 157nm upon request.
