This is a 092-0225FR+50 25.4 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 25.4 mm and a thickness at the center of 6 mm.
The mirror's geometry is spherical, with a radius of curvature (R1) of 50 mm, resulting in an effective focal length (EFL) of 25 mm. This mirror is designed to work within the wavelength range of 600-1100 nm.
The mirror is made of N-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and wide transparency range. The front surface of the mirror is coated with EKSMA's enhanced silver coating, designated as 'eks enhsil600110045'. This coating provides high reflectivity within the specified wavelength range, making it suitable for various applications.
