This is a 095-0130R-5000 protected gold spherical plano-concave mirror, sourced from EKSMA Optics. The mirror has a diameter of 50.8 mm and a thickness of 10 mm at the edge. It is designed for use with a wavelength of 900 nm and is made from N-BK7 Schott glass, a popular choice for its high refractive index and low dispersion.
The mirror's geometry is spherical, with a radius of curvature (R1) of -5000 mm, resulting in an effective focal length (EFL) of -2500 mm. This curvature and the mirror's concave shape make it suitable for a variety of applications, including focusing and collimating light.
The mirror's front surface is coated with EKS 0030protgold900, a protected gold coating that provides high reflectivity in the infrared region of the spectrum. This coating is designed to withstand the rigors of regular use, making this mirror a reliable choice for demanding applications.
