ISP Optics CF-PX-50-200 Plano Convex Lens

The ISP Optics CF-PX-50-200 is a precision plano-convex lens made from high-purity calcium fluoride (CaF₂). Measuring 50.8 mm in diameter with a 200 mm focal length, this lens delivers excellent transmission from ultraviolet (UV) to infrared (IR) wavelengths. CaF₂ provides low absorption, a high laser damage threshold, and exceptional resistance to thermal shock, making it ideal for demanding applications in spectroscopy, laser systems, imaging, and other scientific or laboratory optical setups.
