This is a 095-0130R-2000 protected gold spherical plano-concave mirror, sourced from EKSMA Optics. The mirror has a diameter of 50.8 mm and a thickness of 10 mm at the edge. It is designed for use with a wavelength of 900 nm and features a spherical geometry with a radius of curvature of -2000 mm, resulting in an effective focal length of -1000 mm.
The mirror is made from N-BK7 Schott glass, a popular material for optical components due to its excellent optical properties and high damage threshold. The front surface of the mirror is coated with EKS 0030protgold900, a protected gold coating that provides high reflectivity in the infrared region of the spectrum. This coating is designed to withstand harsh environmental conditions, making the mirror suitable for use in a wide range of applications.
