This is a 095-0125FR-800 model mirror, manufactured by EKSMA Optics, with a diameter of 50.8 mm and a thickness of 10mm at the edge. The mirror is designed as a plano-concave spherical mirror, with a radius of curvature (R1) of -800 mm, resulting in an effective focal length (EFL) of -400 mm.
The mirror is made of N-BK7 Schott glass, a popular choice for its high homogeneity, low auto-fluorescence, and excellent transmission in the visible and near-infrared spectral ranges. This particular mirror is designed to operate within the wavelength range of 600-1100 nm.
The mirror's front surface is coated with an enhanced silver coating, designated as 'eks enhsil600110045'. This coating provides high reflectivity across the specified wavelength range, making it suitable for various applications that require high-performance mirrors.
