87-690 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=50mm Protected Gold 700-2000nm
The 87-690 is a 25 mm diameter Plano-Convex Spherical Mirror, designed and manufactured by Edmund Optics. This mirror is part of their extensive catalog of optical elements, sourced from various vendors worldwide. The mirror features a convex base shape, constructed from N-BK7 Schott glass, a popular choice for its excellent optical properties and high damage threshold.
The mirror's geometry includes a 25 mm diameter, with a thickness of 2.22 mm at the edge and 3 mm at the center. The effective focal length (EFL) is 50 mm, making it suitable for a wide range of optical applications. The mirror's curvature is spherical, with a radius of curvature (R1) of 100 mm.
The mirror's front surface is coated with a protected gold coating, designed to enhance its performance in the 700-2000nm wavelength range. This coating provides high reflectivity and durability, making it ideal for use in demanding environments.
