This is a 091-3130R-250 UVFS Protected Gold Spherical Plano-Concave Mirror, a high-quality optical component sourced from EKSMA Optics. The mirror has a circular base shape with a diameter of 12.7 mm and a thickness of 6 mm at the edge. It is designed to focus or collimate light at a focal length of -125 mm, as determined by its effective focal length (EFL).
The mirror's curvature is spherical, with a radius of curvature (R1) of -250 mm. This curvature allows the mirror to reflect light rays to a single focal point, making it suitable for various optical applications. The mirror is made from UVFS material, identified as UVFS Mal- 1965 in the item data, and is coated with a protective gold layer (eks 0030protgold900) on the front surface.
The protective gold coating enhances the mirror's reflectivity in the near-infrared region, specifically at the 900 nm wavelength. This makes the mirror ideal for applications that require high reflectivity in this spectral range, such as optical communication systems, biomedical imaging, and laser-based metrology.
