43-826 12 mm Dia. N-BK7 Concave-Convex Spherical Mirror; EFL=6mm Protected Gold 700-10000nm

This is a 12 mm diameter concave mirror from Edmund Optics, designed with a spherical shape and a focal length (EFL) of 6mm. The mirror is made of N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. The mirror's concave shape is defined by a radius of curvature of -12mm on both sides, indicating a concave-convex geometry.

The mirror's thickness at the edge is 3mm, providing structural rigidity while minimizing unnecessary weight. The coating on the front surface is a protected gold coating, designed to operate within the wavelength range of 700-10000nm. This coating ensures high reflectivity and durability, making it suitable for a wide range of applications, including but not limited to, spectroscopy, interferometry, and beam shaping.
