Plano concave cylindrical mirrors, the reflecting surface is a cylindrical surface, and the parallel incident light reflected by the cylindrical surface can converge to a line with a positive focal length. The focal length of the plano concave cylindrical mirror is half of the radius of curvature of the cylindrical surface. Suitable for light focusing applications.
Borisun optics provides spherical mirrors without coating and with reflective film. The options of reflective film include ordinary protective aluminum coating, protective ultraviolet reflective aluminum coating, protective silver coating, protective gold coating or dielectric high reflection coating.
