This is a 097-0125R-300 Protected Silver Plano-Concave Spherical Mirror, sourced from EKSMA Optics. The mirror has a diameter of 76.2 mm and a thickness of 12.7 mm at the edge. It is designed for use with a wavelength of 400 nm and is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties.
The mirror's geometry is spherical, with a radius of curvature (R1) of -300 mm, which results in a focal length (EFL) of -150 mm. This curvature and focal length make it suitable for various applications that require concave mirrors.
The mirror is coated with EKS 0025protsil 4000 on the front side, which is a protected silver coating. This coating enhances the mirror's reflectivity and durability, making it suitable for use in environments where the mirror may be subject to wear and tear.
