092-0125R-50 25.4 mm Dia. N-BK7 Protected Silver Plano-Concave Spherical Mirror; t=6mm 400nm

This is a 092-0125R-50 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 refractive index and low dispersion.

The mirror's concave shape, with a radius of curvature (R1) of -50 mm, allows for the creation of a real image at a distance determined by the mirror's effective focal length (EFL) of -25 mm. This makes it suitable for various applications where light needs to be focused or collected, such as in imaging systems, interferometers, or laser resonators.

The mirror's front surface is coated with EKS 0025protsil 4000, a protected silver coating that offers high reflectivity across the visible spectrum. This coating is designed to withstand environmental conditions better than traditional silver coatings, providing enhanced durability and longevity.
