43-466 25 mm Dia. N-BK7 Concave-Convex Spherical Mirror; EFL=50mm Protected Aluminum 400-2000nm

This 25 mm diameter concave mirror, sourced from Edmund Optics, offers a focal length of 50mm, making it ideal for a variety of optical applications. The mirror is made from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including low autofluorescence and a wide transmission range. The N-BK7 Schott material ID ensures consistency and reliability in the mirror's performance.

The mirror's geometry is spherical, with a radius of curvature of -100mm for both the front and back surfaces. This curvature, combined with the mirror's diameter, contributes to its concave shape. The mirror has a thickness of 3mm at the edge, providing structural integrity without compromising its optical performance.

The mirror's coating is a protected aluminum, designed to enhance its reflectivity across a wide spectrum, from 400nm to 2000nm. This broad wavelength range makes the mirror versatile, suitable for use in various applications, from ultraviolet (UV) to near-infrared (NIR) spectrum.

The mirror's coating is identified as edm protal452008000, indicating a specific coating type and process. This coating is designed to protect the aluminum from oxidation and other environmental factors, ensuring the mirror maintains its performance over time.
