This is a 095-0130R-6000 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 shape with a radius of curvature of -6000 mm.
The mirror is made from N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and high damage threshold. The mirror's front surface is coated with EKS 0030protgold900, a protected gold coating that provides high reflectivity in the infrared region of the spectrum.
The mirror's concave surface has an effective focal length (EFL) of -3000 mm, making it suitable for use in various optical systems, including lasers and interferometers. The mirror's large diameter and high-quality coating make it an excellent choice for applications requiring high precision and reliability.
