Plano-Convex Lens, Calcium Fluoride, 25.4 mm, 100 mm FL, 180-8000 nm

The CAPX13 is a Plano-Convex Infrared Lens, made of CaF₂ material. It has a diameter of 25.4 mm, and an effective focal length of 100 mm. Calcium Fluoride lenses are an excellent choice of material for making lenses for UV to NIR wavelengths (180 nm - 8 μm). It has high average transmission and low chromatic aberration compared to various IR materials. In NIR regime, CaF₂ exhibits very low GVD which makes it suitable for applications using femtosecond IR pulses.
