K9 Plano concave spherical mirror
PRODUCT CATEGORIES
- Plano concave spherical mirror, the reflecting surface is a part of the spherical surface, and the parallel incident light can converge to a point after being reflected by the spherical surface, with a positive focal length. The focal length of the plano concave spherical mirror is half of the radius of curvature of the spherical surface.
- 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.
