Protected Silver Mirror
Protected Silver Mirrors are precision optical mirrors featuring a silver reflective coating with a protective overcoat layer to improve environmental stability and durability. Silver coatings provide excellent broadband reflectivity, especially in visible and infrared wavelengths, and the protective layer helps reduce oxidation and extends coating lifetime. Chenyu Optics manufactures protected silver mirrors in BK7 and fused silica with custom wavelength coatings.
Protected Silver Mirror Overview
Protected Silver Mirrors are precision optical mirrors featuring a silver reflective coating with a protective overcoat layer to improve environmental stability and durability.
Silver coatings provide excellent broadband reflectivity, especially in visible and infrared wavelengths. The protective layer helps reduce oxidation and extends coating lifetime, making these mirrors suitable for demanding optical systems requiring stable long-term performance.
Chenyu Optics supports custom protected silver mirror manufacturing according to customer drawings, including custom substrate material, dimensions, surface accuracy and coating design for prototype and repeat production.
