Our plano-convex CaF₂ lenses have a positive focal length, can be used either for focusing collimated light or for collimating a point source. These lenses are all made of vacuum grade UV material, the uncoated lenses have high transmission (>90%) from 200-7000nm. If your application needs even higher transmission at 3~5μm, IR1 AR coating (R<1.5%@ 3~5μm) is available.
