This is a 092-0125FR-4000 25.4 mm Dia. N-BK7 Enhanced Silver Plano-Concave 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 of 6 mm at the edge.
The mirror's geometry is spherical, with a radius of curvature (R1) of -4000 mm, which results in an effective focal length (EFL) of -2000 mm. This concave mirror is designed to focus light to a single point, making it ideal for various applications in optical systems.
The mirror is made of N-BK7 Schott, a popular optical glass due to its excellent optical properties and wide transmission range. It is suitable for use in wavelengths between 600 and 1100 nm.
The front surface of the mirror is coated with EKSMA's enhanced silver coating, specifically the EKS ENHSIL600110045 coating. This coating provides high reflectivity in the specified wavelength range, enhancing the mirror's performance in its intended application.
