43-583 76.2 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=203.2mm Protected Aluminum 400-2000nm

This 43-583 optical mirror, sourced from Edmund Optics, is a 76.2 mm diameter concave spherical mirror with a focal length (EFL) of 203.2mm. The mirror is made from borofloat33, a borosilicate glass with low thermal expansion, making it an excellent choice for applications requiring high temperature stability and resistance to thermal shock.

The mirror's concave spherical shape is defined by a radius of curvature (R1) of -406.4mm. This shape is ideal for applications requiring light concentration or reflection, such as in imaging systems, beam expanders, or laser applications. The mirror has a thickness of 12.7mm at the edge, providing rigidity and stability.

The mirror is coated with a protected aluminum coating, designated as edm dprotal300200000, which offers high reflectivity across a broad spectrum, from 400nm to 2000nm. This wide spectral range makes the mirror suitable for various applications, including ultraviolet (UV), visible, and infrared (IR) light. The protective layer on the coating enhances the mirror's durability and resistance to environmental factors, ensuring longevity and reliability.

The mirror's specifications and coating make it a versatile and high-performance component in various optical systems. It is currently in stock, as indicated by its weblink status, and more information can be found on the Edmund Optics website.
