This is a 095-3130R-100 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 to be used at a wavelength of 900 nm.
The mirror's geometry is spherical, with a radius of curvature (R1) of -100 mm, resulting in a focal length (EFL) of -50 mm. This negative focal length indicates that the mirror is concave, focusing light to a point on the same side of the mirror as the light source.
The mirror is coated with EKS 0030protgold900 on the front surface, which is a protected gold coating specifically designed for use at a wavelength of 900 nm. The protection layer enhances the durability of the coating, making it suitable for use in various environments.
The material of the mirror is UVFS mal- 1965, which is a type of fused silica. This material is known for its excellent optical properties, including high transparency and low thermal expansion.
