092-0125R-1000 25.4 mm Dia. N-BK7 Protected Silver Plano-Concave Spherical Mirror; t=6mm 400nm

This is a 092-0125R-1000 protected silver plano-concave spherical 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 400 nm and is made from N-BK7 Schott glass, a popular choice for its high homogeneity and low auto-fluorescence.

The mirror's geometry is spherical, with a radius of curvature (R1) of -1000 mm, resulting in a focal length (EFL) of -500 mm. This curvature and the mirror's concave shape make it suitable for focusing or collimating light in various optical systems.

The mirror's coating is EKS 0025protsil 4000, a protected silver coating that provides high reflectivity and durability. This coating is specifically designed for use in the ultraviolet region, making it ideal for applications that require high performance at 400 nm.
