This is a 32-822 50.8 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror, a high-quality optical component designed for use in a wide range of applications. The mirror is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The mirror has a base shape of a circle, with a diameter of 50.8 mm and a thickness edge of 12.7 mm. It boasts an effective focal length (EFL) of 508 mm, making it suitable for use in systems that require precise focusing. The mirror's geometry is spherical, with a radius of curvature (R1) of -1016 mm, which contributes to its high optical performance.
The mirror is made from borofloat33, a type of glass known for its excellent optical properties and durability. It is coated with a protected gold coating, specifically designed for the wavelength of 588 nm, which enhances its reflectivity and ensures longevity. The coating on the front surface is edm prgold 700-10000, providing a broad spectral range from 700 to 10000 nm.
