TFAG-50.8C08-10 Mirror

[Features]
· A planar total reflection mirror coated with silver (Ag) that can obtain high reflectance in a wide wavelength range from visible light to infrared.
· Since silver has been coated with a protective membrane, it is possible to use it with little or no oxidation over long periods of time.
· Higher reflectance than aluminum mirrors can be obtained in the wavelength range from visible to infrared.
· The incidence dependence is smaller than with dielectric multilayer film, and it can be used arranged at various incidence angles.
· As it has been coated with a protective film, scratches are unlikely to remain when wiped with a cloth, etc.
· * For long-term storage, use a de-oxidizer to prevent the oxidation of silver.
· * Loss of light may occur due to silver absorption when transmitting light with multiple mirrors.
· * Use a multi-layered dielectric film mirror (TFVM) for incidence of 0°-45°.
· * Reflectance for the specification shows average reflectance values of P polarization and S polarization.
· * Reflectance may vary according to the polarization of the incident beam.
