87-672 50 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=25mm Enhanced Aluminum 450-650nm

The 87-672 is a 50 mm diameter Plano-Convex Spherical Mirror, sourced from the renowned optical components vendor, Edmund Optics. This mirror is designed for use in the visible light spectrum, specifically optimized for the 450-650nm range.

The mirror's geometry is characterized by a convex shape with a 50 mm radius of curvature (R1), making it suitable for a wide range of optical applications. The mirror's thickness varies from 1.3 mm at the edge to 8 mm at the center, providing structural rigidity and stability.

The mirror is fabricated from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. This material is particularly suitable for applications in the visible spectrum due to its low dispersion and high transmission.

The mirror's surface is coated with Enhanced Aluminum, a highly reflective coating that enhances its performance in the specified wavelength range. The Enhanced Aluminum coating provides a high reflectivity of 87-93%, ensuring optimal light reflection and minimizing losses.

The mirror's effective focal length (EFL) is 25 mm, a feature that determines its focusing properties. This EFL makes the mirror suitable for use in various optical systems, including beam expanders, collimators, and focusing systems.
