Lenses have many applications ranging from the simple collection of a laser beam to precision imaging and image transfer. Lenses are classified as single lenses, cylindrical lenses and achromatic lenses. These lenses are made of BK7, FS,CaF2 and IR material(Si,Sapphire,Ge,YAG etc.). Special focusing systems can be designed by our engineers upon request.
