Protective Aluminum Coated Plano Concave Mirror
Protective aluminum coated plano-concave spherical reflector, the reflective surface is part of the spherical surface, parallel incident light can be reflected by the spherical surface to converge to a point, 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. Material is H-K9L glass.
We provide reflectors without coating and with reflective coating. The reflective coating options include ordinary reinforced aluminum coating, protective UV reflective aluminum coating, protective silver coating, protective gold coating, dielectric high reflective coating D01, dielectric high reflective coating D02, dielectric high reflective coating D03, and dielectric high reflective coating D04.
