61-6872-25 Gold Flat Mirror φ20mm Glass Round TFG-20C05-10
Features
- It is a total reflection mirror coated with a high reflectivity gold film in a wide band in the near infrared and infrared region.
- The chromium film is very thinly undercoated to strengthen the film adhesion of the gold film.
- Silicon substrates have very strong adhesion of gold film, high thermal conductivity (approximately 111 times better heat dissipation than glass), and superior heat resistance compared to glass substrates.
- Since it is a metal coating, the reflectivity and reflectivity wavelength characteristics do not change significantly depending on the incident angle.
- Gold coat has very high reflectivity in the infrared.
- Any light that is not reflected is absorbed by the film and does not pass through.
- We also offer an ultra-wideband dielectric mirror (TFMS-4/20) that does not absorb film.
- Pyrex (R) is a registered trademark of Corning Corporation.
- * When using with a high power laser, it is necessary to cool the substrate using a gold mirror (TFGS) of the silicon substrate.
- * It is strictly prohibited to wipe the gold film with paper or cloth.
- * If you touch the membrane, it will scratch.
- * Use an air blower to clean the membrane surface.
- * The reflectance of the specification is expressed as the average value of the reflectance of P-polarized light and S-polarized light.
