SILVER MIRROR


In the visible to near infrared has a very high reflectivity, in the range of 450-2000um the average reflectivity Ravg>97.5%, it is the highest reflectivity of all metal mirrors, while in the band range of 2-20um has a high reflectivity, Ravg>96%.Because the silver film is soft and easy to scratch and oxidize, the outermost layer of these mirrors is plated with a 100nm thick SiO2 film, but it is still necessary to avoid a high humidity environment during use, and the wiping needs to be more careful. Due to their high reflectivity in the 450 nm-20 µm range, these mirrors are well suited for use in femtosecond lasers.
