43-470 50 mm Dia. N-BK7 Concave-Convex Spherical Mirror; EFL=50mm Protected Aluminum 400-2000nm

This 50 mm diameter concave mirror is a high-quality optical component sourced from Edmund Optics. It features a concave-convex spherical geometry with radii of curvature of -100 mm for both surfaces, making it suitable for a wide range of optical applications. The mirror has a focal length (EFL) of 50 mm, which is the distance from the mirror's surface to the focal point.

The mirror is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. The glass has a diameter of 50 mm and a thickness of 6 mm at the edge. The coating on the front surface is EDM PROTAL452008000, a protected aluminum coating that provides high reflectivity in the 400-2000 nm wavelength range.

This mirror is a versatile and reliable choice for applications that require high-quality reflective optics. It is currently in stock, according to the vendor's website, and more information can be found at the provided weblink.
