87-667 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=25mm Enhanced Aluminum 450-650nm

This 87-667 optical mirror, sourced from Edmund Optics, boasts a 25 mm diameter and a 25 mm effective focal length (EFL). Its base shape is circular, and it features a convex curvature with a 50 mm radius of curvature (R1). The mirror's thickness varies from 1.41 mm at the edge to 3 mm at the center, providing robustness and stability.

The mirror is crafted from N-BK7, a high-quality borosilicate glass known for its excellent optical properties, including a low coefficient of thermal expansion and high homogeneity. This material is identified by the vendor as "n-bk7 schott," indicating its Schott origin, a renowned glass manufacturer.

The mirror's coating is an enhanced aluminum coating, designed to optimize reflectance within the 450-650 nm wavelength range. This coating, denoted as "edm enh al 0 2002000," ensures high-quality reflection, making this mirror suitable for various applications within this spectral range.
