43-339 25.4 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=50.8mm Protected Aluminum 400-2000nm

This 25.4 mm diameter concave spherical mirror, sourced from Edmund Optics, is a high-precision optical component designed for use in a wide range of applications. The mirror's base shape is circular, and it features a concave geometry with a radius of curvature (R1) of -101.6 mm. This curvature, combined with the mirror's effective focal length (EFL) of 50.8 mm, makes it suitable for focusing or collimating light in various optical systems.

The mirror is made from borofloat33, a type of borosilicate glass known for its excellent optical properties and high resistance to thermal shock. The glass has a thickness of 6.35 mm at the edge, providing structural rigidity and minimizing the risk of deformation due to external forces.

The mirror's surface is coated with a protected aluminum coating, identified as 'edm dprotal300200000'. This coating is designed to provide high reflectivity across a broad spectrum, from 400 to 2000 nm. The 'protected' designation indicates that the coating is robust and resistant to oxidation and other forms of environmental degradation, ensuring long-term performance and durability.
