092-0115R-2500 25.4 mm Dia. N-BK7 Protected Aluminium Spherical Plano-Concave Mirror; t=6mm 300nm

This is a 092-0115R-2500 protected aluminium spherical plano-concave mirror, sourced from EKSMA Optics. The mirror has a diameter of 25.4 mm and a thickness of 6 mm at the edge. It is designed for use with a wavelength of 300 nm and is made from N-BK7 Schott glass, a popular choice for its excellent optical properties and high damage threshold.

The mirror's geometry is spherical, with a radius of curvature (R1) of -2500 mm, resulting in a focal length of -1250 mm. This negative focal length indicates that the mirror is concave, focusing light to a point on the same side of the mirror as the light source.

The mirror is coated with EKS 0015PROTAL 3000 on the front surface, a protective aluminium coating that enhances the mirror's durability and resistance to environmental factors. This coating is specifically designed for use with ultraviolet light, making it an ideal choice for applications in this wavelength range.
