TFAN-3040R06-20 Plane Mirror

[Features]
· It is a mirror with aluminum deposition on the flat substrate polished with high precision.
· High reflectance can be achieved in various incidence angles.
· There are ones with only aluminum film coating (TFAN/TFAQN) as well as ones with aluminum film with protective coating (TFA/TFAQ) to prevent scratches.
· Can be used as a mirror for visible light and near infrared light.
· Low expansion, high rigidity, high surface accuracy mirror (TFAQ/TFAQN) using synthetic quartz substrate is also available.
· Pyrex® is a registered trademark of Corning Inc.
· * Aluminum mirrors without protective coating (TFAN/TFAQN) are easily damaged, and film will become oxidized.
· * Never rub the mirror surface with paper or cloth.
· * For long-term storage, use a de-oxidizer to prevent the oxidation of aluminum.
· * Loss of a large amount of light may occur due to aluminum film absorption when transmitting light with multiple mirrors.
· * Use a dielectric multi-layer film mirror (TFM, etc.).
· * 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.
