49-596 25.4 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=203.2mm Uncoated

This is a 49-596 25.4 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror, sourced from the reputable optical components vendor, Edmund Optics. The mirror, which is uncoated, boasts a base shape of a circle and a sub-type of a curved mirror with a concave geometry.

The mirror has a diameter of 25.4 mm and a thickness at the edge of 0.25 mm. The effective focal length (EFL) of this mirror is 203.2 mm, and its radius of curvature (R1) is -406.4 mm, indicating a concave shape. The mirror is made of borofloat33, a material known for its excellent optical properties and durability.

The mirror is designed to operate at a wavelength of 588 nm. It features a spherical shape, which is the simplest and most common type of curved mirror. The spherical shape ensures that all light rays that strike the mirror parallel to the axis will converge at a single point, the focal point, making it ideal for various optical applications.

Please note that the mirror is uncoated. While uncoated mirrors can be suitable for certain applications, they may not perform as well as coated mirrors in others, especially in terms of reflectivity. Therefore, users should consider their specific needs and requirements when choosing this mirror.
