This is a front surface concave-convex mirror designed for illumination systems, available from Qioptiq Photonics. The mirror has a diameter of 31.5 mm and a center thickness of 2 mm. It is designed with an effective focal length (EFL) of 14 mm, making it suitable for a variety of applications.
The mirror's curvature is defined by two radii (r1 and r2), both of which are -28 mm, indicating a concave shape. The mirror is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and high damage threshold.
The mirror is coated with qio al ralvis aoi 45 on the front surface. This coating is designed to enhance reflectivity in the spectral range of 400-700 nm, making it ideal for use in applications that require high light transmission in the visible spectrum.
The mirror's shape is spherical, a common choice for its ease of manufacturing and versatility. According to the vendor's information, this mirror is in stock and available for immediate purchase.
