This is a 091-0125FR-50 12.7 mm Dia. N-BK7 Enhanced Silver Plano-Concave Spherical Mirror, a high-quality optical component sourced from EKSMA Optics. The mirror has a diameter of 12.7 mm and a thickness of 6 mm at the edge, making it suitable for a wide range of optical applications.
The mirror's curvature is spherical, with a radius of curvature (R1) of -50 mm. This concave shape allows for the focusing of light, making it ideal for use in systems where light needs to be concentrated onto a single point. The effective focal length (EFL) of this mirror is -25 mm, which is the distance from the mirror's surface to the point where the light focuses.
The mirror is made from N-BK7, a popular optical glass known for its excellent optical properties. This material is especially suitable for use in the visible and near-infrared regions of the spectrum, with a wavelength range of 600-1100 nm.
The mirror's surface is coated with EKSMA's enhanced silver coating, which is designed to provide high reflectivity over a broad spectral range. This coating, denoted as 'eks enhsil600110045', ensures optimal performance for this mirror in its intended wavelength range.
