49-618 50.8 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=203.2mm Protected Gold 700-10000nm

This is a 49-618 model spherical mirror, boasting a 50.8 mm diameter and a protected gold coating suitable for wavelengths between 700 and 10000 nm. The mirror's concave shape, with a 406.4 mm radius of curvature (RoC), contributes to a 203.2 mm effective focal length (EFL).

The mirror is made of borofloat33, a low-thermal-expansion borosilicate glass, which ensures dimensional stability and resistance to thermal shock. Its 12.7 mm thickness along the edge contributes to overall structural rigidity.

The protected gold coating (edm prgold 700-10000) on the front surface enhances the mirror's reflectivity in the specified wavelength range. This type of coating is known for its high damage threshold and resistance to environmental factors, making it suitable for various applications.
