49-611 25.4 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=203.2mm Enhanced Aluminum 450-650nm

This is a 49-611 model spherical mirror, boasting a 25.4 mm diameter and a thickness of 6.35 mm at the edge. The mirror is concave in shape, designed with a radius of curvature (R1) of -406.4 mm, which is equivalent to a focal length of 203.2 mm.

The mirror is made of borofloat33, a type of borosilicate glass known for its high thermal resistance and excellent optical transmission properties. This particular mirror is coated with enhanced aluminum, specifically designed for use in the 450-650 nm wavelength range. This coating enhances the mirror's reflectivity, making it ideal for various applications within this spectral range.

The mirror's geometry and material properties make it suitable for use in a wide range of optical systems, including beam expanders, collimators, and focusing systems.
