091-0125R-250 12.7 mm Dia. N-BK7 Protected Silver Plano-Concave Spherical Mirror; t=6mm 400nm

This 091-0125R-250 optical mirror, sourced from EKSMA Optics, is a protected silver plano-concave spherical mirror with a diameter of 12.7 mm and a thickness of 6 mm at the edge. The mirror's design includes a concave base shape with a radius of curvature (R1) of -250 mm, resulting in a focal length of -125 mm.

The mirror is made of N-BK7 Schott glass, a popular material for its high refractive index and low dispersion, making it suitable for a wide range of optical applications. The mirror's coating is EKS 0025protsil 4000, specifically designed for the front surface, enhancing its reflectivity and durability.

This mirror is designed to operate at a wavelength of 400 nm, making it suitable for applications such as ultraviolet (UV) spectroscopy, fluorescence microscopy, and other UV-based optical systems. The mirror's protected silver coating ensures high reflectivity and resistance to tarnish, making it a reliable choice for various optical setups.
