CaF2 Plano Convex Lens

A plano-convex lens is a positive focal length lens with a plane on one side and a convex on the other. It is used to concentrate parallel light, or convert point light sources into parallel light. Widely used in telescope, microscope, sight, laser, optical fiber and other products.Calcium fluoride crystals with high hardness, strong mechanical shock and thermal shock resistance, wide scope of pervious to light (190 nm to 10000 nm), in the ultraviolet, visible and infrared wavelengths with good transmittance, so they are widely used in laser and infrared optical, ultraviolet, and other fields, the concrete can be used as a testing instrument, laser power infrared Windows, gas liquid system, imaging system, etc.

Sunday Optical Plano convex lens diameter range from 0.35mm to 600mm, Material can be optical glass, Quartz, Sapphire, CaF2, MgF2, Infrared glass such as ZnSe, CaF2, Ge, Si.
