87-697 50 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=200mm Protected Gold 700-2000nm

The 87-697 is a 50 mm diameter Plano-Convex Spherical Mirror, sourced from the renowned optical components vendor, Edmund Optics. This mirror is designed with a convex base shape, featuring a 200 mm effective focal length (EFL), making it suitable for a wide range of optical applications.

The mirror is crafted from N-BK7, a high-quality borosilicate glass known for its excellent optical properties. The N-BK7 Schott material ensures high transmission and low auto-fluorescence, making it an ideal choice for applications that require high-precision optics.

The mirror's geometry includes a 4.21 mm thickness at the edge, gradually increasing to 5 mm at the center, providing robustness and stability. The curvature of the mirror is defined by a 400 mm radius (R1), which is crucial for determining the mirror's optical performance.

The mirror's surface is coated with a protected gold coating, specifically designed for the wavelength range of 700-2000nm. This coating enhances the mirror's reflectivity within this spectral range, making it suitable for various applications, including but not limited to, beam combining, interferometry, and laser systems.
