87-695 50 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=50mm Protected Gold 700-2000nm

The 87-695 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 700-2000nm wavelength range, making it suitable for a wide range of applications, including but not limited to, imaging, beam shaping, and laser systems.

The mirror's geometry is defined by a 50 mm diameter and a 50 mm effective focal length (EFL), ensuring a high-quality, focused beam. The convex surface of the mirror has a radius of curvature (R1) of 100 mm, contributing to its focusing capabilities. The mirror's thickness varies from 1.83 mm at the edge to 5 mm at the center, providing structural rigidity and resistance to deformation.

The mirror is crafted from N-BK7 Schott glass, a popular choice in the optical industry due to its excellent optical properties and high damage threshold. This material ensures high transmission and low dispersion, making it ideal for applications that require high-precision optics.

The mirror's front surface is coated with a protected gold coating, designed to enhance reflectivity in the 700-2000nm wavelength range. This coating not only improves the mirror's performance but also provides protection against environmental factors, ensuring longevity and reliability.
