092-0125FR-50 25.4 mm Dia. N-BK7 Enhanced Silver Plano-Concave Spherical Mirror; t=6mm 600-1100nm

This is a 092-0125FR-50 mirror, a high-quality optical component sourced from EKSMA Optics. It is a curved mirror with a concave base shape and a circular diameter of 25.4 mm. The mirror has a thickness of 6 mm at the edge, making it robust and durable.

The mirror's geometry is spherical, with a radius of curvature (R1) of -50 mm. This results in a focal length (EFL) of -25 mm, indicating that it is a negative or concave lens. The mirror is designed to work within the wavelength range of 600-1100 nm, making it suitable for a wide range of optical applications.

The mirror is made of N-BK7, a popular optical glass from Schott. This material is known for its excellent optical properties, including high transmittance and low autofluorescence.

The mirror's surface is coated with enhanced silver, which provides high reflectivity across the specified wavelength range. The coating is identified as 'eks enhsil600110045'. This coating ensures that the mirror efficiently reflects light, enhancing the performance of the optical system in which it is used.
