This is a 097-3125R-2000 protected silver plano-concave spherical mirror, sourced from EKSMA Optics. The mirror has a diameter of 76.2 mm and a thickness of 12.7 mm at the edge. It is designed for use at a wavelength of 400nm and features a UVFS protected silver coating on the front surface, identified as 'eks 0025protsil 4000'.
The mirror's geometry is spherical, with a radius of curvature (R1) of -2000 mm, resulting in a negative focal length of -1000 mm. This indicates that the mirror is concave, focusing light to a point on the opposite side of the mirror.
The mirror's material is UVFS mal- 1965, which is specifically designed for use in ultraviolet applications. The mirror is in stock and available for immediate purchase, as indicated by its weblink status.
