Details

The K9 Plane Concave Spherical Mirror has a reflective surface that is a part of a sphere. Parallel incident light rays can converge to a point through reflection on the sphere, and it has a positive focal length.
Concave mirrors are commonly used in applications that require light collection. When light reaches the surface of a concave reflector, the surface contour of the reflector will focus the reflected light on a point. The focal length of a flat concave spherical mirror is half the radius of curvature of the sphere. The focal length of a flat concave spherical mirror is half the radius of curvature of the sphere. Guangtan Intelligent provides spherical mirrors without coating or coated with reflective film. The reflective film options include ordinary protective aluminum film, protective ultraviolet reflective aluminum film, protective silver film, protective gold film, or dielectric high reflective film.
Guangtan Intelligent is a standard supplier of reflective mirror optics. We not only provide a large number of standard reflective mirror products in stock, but also customize reflective mirrors according to your needs.
Precautions for use:When taking the reflector, please wear gloves and do not directly use your hands. Hold it with non optical surfaces such as frosted edges. Do not wipe the surface of the metal film reflector as physical contact may damage the optical surface. When cleaning, use air blowing to wipe the surface of the optical component.
