092-0125FR-700 25.4 mm Dia. N-BK7 Enhanced Silver Plano-Concave Spherical Mirror; t=6mm 600-1100nm

This is a 092-0125FR-700 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 edge of 6 mm, making it suitable for a wide range of optical applications.

The mirror's geometry is spherical, with a radius of curvature (R1) of -700 mm, which results in a focal length of -350 mm (EFL). This negative focal length indicates that the mirror is a concave mirror, which reflects light rays towards a single point, the focal point.

The mirror is made of N-BK7 Schott glass, a popular material in the optical industry due to its excellent optical properties and high damage threshold. The coating on the front surface of the mirror is EKSMA's enhanced silver coating, designed for use in the 600-1100 nm wavelength range. This coating provides high reflectivity and durability, making it ideal for use in demanding optical systems.
