Silver (Ag) Mirrors are economical and universal VIS-IR mirrors best suitable for visual, low & medium energy applications. Protected and ultrafast optimized options available. What is Silver (Ag) coated mirror? Silver (Ag) mirror is optical component coated with metallic silver coating (and usualy protective coating layer on top of it). These mirrors have quite broad reflection range which also depends on dielectric protective coating, but it is within visible and infrared wavelengths. Although Silver (Ag) mirrors have largest laser induced damage threshold (LIDT) among other Alien Photonics metallic mirrors (Gold and Aluminum), we are still recommending to limit their use to visual, low and medium energy applications (such as microscopes or low power lasers) How Silver (Ag) Mirrors are manufactured? Process is quite similar to broad band BBHR mirrors, and starts by preparing optical substrate (polishing and inspecting it). Using optical coating technologies, that substrate is coated with thin film Silver (Ag) metallic layer, forming the mirror. Alien photonics Silver (Ag) mirrors are then coated with either standard protective dielectric layer or special enhancing layer to optimize these mirrors for ultrashort pulses. How to handle Silver (Ag) Mirrors? Alien Photonics silver (Ag) mirrors are upgraded with protective coatings which protects the silver thin film from oxidation and physical damage. However, Alien Photonics still recommends to refrain from using excessive force when cleaning Ag mirrors.
