This 35 mm diameter concave mirror, sourced from Edmund Optics, boasts a 15mm effective focal length (EFL) and is crafted from N-BK7 Schott glass. The mirror's base shape is circular, with a thickness of 6mm at the edge. It features a concave-convex spherical geometry, with both radii of curvature (r1 and r2) measuring -30mm, suggesting a symmetrical design.
The mirror's coating is a protected aluminum, designed to enhance reflectivity within the 400-2000nm wavelength range. This coating is identified by the vendor-specific code "edm protal452008000". The mirror's spherical shape ensures a consistent curvature, making it suitable for a wide range of optical applications.
