Details

The K9 Plano Concave Cylindrical Mirror has a cylindrical reflective surface, and parallel incident light rays can converge into a line through cylindrical reflection, with a positive focal length. The focal length of a flat concave cylindrical mirror is half the radius of curvature of the cylindrical surface. Suitable for light focusing applications.
Guangtan Intelligent provides cylindrical 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, and protective gold film.
Silver plated mirrors are susceptible to environmental conditions and improper operation, so special care is required. Fingerprints, contact with grinding surfaces, and high humidity or high temperature environments can all reduce the effectiveness of protective coatings, leading to oxidation and degradation of the coating. It is recommended to use latex gloves or similar protective tools to prevent oil and other residues on the user's fingers from contaminating the surface of optical components. Even if these preventive measures are taken, caution should be exercised not to touch the mirror and edges. Silver plated reflectors should be used and stored in a room temperature environment with extremely low humidity.
