32-817 50.8 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=304.8mm Uncoated

This is a 32-817 50.8 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror, sourced from the renowned optical components vendor, Edmund Optics. The mirror, which is uncoated, boasts a high level of precision and is designed for use in a variety of optical applications.

The mirror has a base shape of a circle, with a diameter of 50.8 mm and a thickness at the edge of 12.7 mm. It features a spherical geometry, with a radius of curvature (R1) of -609.6 mm, indicating its concave nature. The effective focal length (EFL) of this mirror is 304.8 mm, making it suitable for use in systems where a longer focal length is required.

The mirror is made from Borofloat33, a type of glass known for its excellent optical properties and high resistance to thermal shock. This makes it an ideal choice for applications that require a high degree of temperature stability.

The mirror is designed to operate at a wavelength of 588 nm. It does not come with any coating, which means it is suitable for use in applications where the uncoated surface is preferred or required.
