This is a 095-0225FR+400 50.8 mm Dia. N-BK7 Enhanced Silver Plano-Convex Spherical Mirror, a high-quality optical component sourced from EKSMA Optics. The mirror has a base shape of a circle with a diameter of 50.8 mm and a thickness at the center of 10 mm.
The mirror's geometry is spherical, with a radius of curvature (R1) of 400 mm, which results in an effective focal length (EFL) of 200 mm. This plano-convex mirror is designed to work within the wavelength range of 600-1100 nm.
The mirror is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and wide transparency range. The front surface of the mirror is coated with EKSMA's enhanced silver coating, specifically EKS ENHSIL600110045, which is designed for high reflectivity within the specified wavelength range.
