49-617 50.8 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror; EFL=152.4mm Protected Gold 700-10000nm

This is a 49-617 50.8 mm Dia. Borofloat λ/4 Precision Concave Spherical Mirror, sourced from the reputable optical components vendor, Edmund Optics. The mirror boasts a protected gold coating, suitable for wavelengths ranging from 700 to 10000nm.

The mirror's geometry is defined by a diameter of 50.8mm, a thickness edge of 12.7mm, and an effective focal length (EFL) of 152.4mm. The concave spherical shape, with a radius of curvature (R1) of -304.8mm, ensures excellent light reflection and focusing capabilities.

The mirror is made of borofloat33, a borosilicate glass known for its high thermal resistance, chemical durability, and excellent transmission properties. This material makes the mirror suitable for various applications, including optical systems exposed to high temperatures or aggressive environments.

The protected gold coating (edm prgold 700-10000) on the front surface enhances the mirror's reflectivity and durability. This coating is specifically designed for use in the infrared region, making it an ideal choice for applications such as thermal imaging, spectroscopy, and beam manipulation.
