092-0125FR-300 25.4 mm Dia. N-BK7 Enhanced Silver Plano-Concave Spherical Mirror; t=6mm 600-1100nm

This is a 092-0125FR-300 model mirror, featuring a 25.4 mm diameter and a thickness of 6mm. It is manufactured by EKSMA Optics, a renowned vendor known for its high-quality optical components. The mirror is made of N-BK7 Schott, a popular optical glass with excellent transmission properties, making it suitable for a wide range of applications.

The mirror's geometry is plano-concave, meaning it has a flat front surface and a curved back surface. The curvature of the back surface is spherical, with a radius of curvature (R1) of -300mm. This curvature results in a focal length (EFL) of -150mm, making it suitable for use in focusing or collimating light.

The mirror is coated with EKSMA's enhanced silver coating, specifically designed for use in the 600-1100nm wavelength range. This coating provides high reflectivity, ensuring optimal performance in its intended application. The coating is applied to the front surface of the mirror, while the back surface remains uncoated, as per the provided item data.
