87-679 25 mm Dia. N-BK7 Plano-Convex Spherical Mirror; EFL=50mm Protected Silver 450-10000nm

The 87-679 is a 25 mm diameter Plano-Convex Spherical Mirror, sourced from the renowned optical components vendor, Edmund Optics. This mirror is designed for use in a wide range of applications, with a protective silver coating that enhances its durability and performance across the spectral range of 450-10000nm.

The mirror's geometry is defined by a base shape of a circle, with a diameter of 25mm. The thickness of the mirror varies from 2.22mm at the edge to 3mm at the center, providing a robust structure that can withstand typical use. The mirror's effective focal length (EFL) is 50mm, making it suitable for applications that require a moderate level of magnification or minification.

The mirror's curvature is spherical, with a radius of curvature (R1) of 100mm. This curvature is designed to provide a wide field of view while maintaining a high level of image quality. The mirror is made from N-BK7 Schott glass, a material known for its excellent optical properties and broad transmission range.

The mirror's coating is a protected silver coating, identified by the vendor code edm dprotsil3001000. This coating is designed to provide high reflectivity while also protecting the mirror from environmental damage. The coating is applied to the front surface of the mirror, ensuring that the mirror's performance is not compromised by contamination or damage to the coating.
