39-865 20 x 20mm Protected Gold Coated; ZERODUR Mirror Protected Gold 700-10000nm

The 39-865 is a 20 x 20mm metallic mirror, specifically designed for use in the wavelength range of 700-10000nm. This mirror is sourced from Edmund Optics, a reputable vendor known for their high-quality optical components.

The mirror is made from ZERODUR, a special glass-ceramic material developed by Schott AG. ZERODUR is characterized by its extremely low thermal expansion coefficient, making it an excellent choice for applications that require high dimensional stability and precise shape over a wide temperature range.

The front surface of the mirror is coated with a protected gold coating, identified as "edm prgold 700-10000". This coating is designed to provide high reflectivity across the specified wavelength range, while also offering excellent environmental stability and resistance to tarnish and corrosion.

The mirror has a rectangular base shape and a thin lens design, with a width and length of 20mm each and a thickness of 3mm. This makes it a compact and lightweight option, ideal for use in systems where space and weight are at a premium.
