This is a 14GM-1-1000 25.4 mm Dia. UVFS Plano-Concave Mirror, a high-quality optical component sourced from Standa. The mirror has a base shape of a circle with a diameter of 25.4 mm and a thickness of 6 mm, making it suitable for a wide range of optical applications.
The mirror's geometry is spherical, with a radius of curvature (R1) of -1000 mm, resulting in a focal length (EFL) of -500 mm. This concave mirror is designed to focus light at a point one focal length away from the mirror's surface.
The mirror is made from UVFS material with the ID 1965, and it is coated with protected gold on the front surface. This coating is specifically designed for a wavelength of 750 nm, enhancing the mirror's performance in this spectral region.
