This product is a curved mirror (concave) with a base shape of a circle, offered by EKSMA Optics. The mirror has a diameter of 12.7 mm and a thickness edge of 6 mm. It is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties. The mirror's geometry includes an effective focal length (EFL) of -500 and a radius of curvature (R1) of -1000.
The mirror is coated with EKS 0025protsil 4000 on the front side, which is a protected silver coating. This coating is designed to provide high reflectivity at a wavelength of 400 nm. The mirror's shape is spherical, which is a common choice for many optical applications due to its simplicity and wide range of uses.
