This is a 095-3130R-1000 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 and features a UVFS protected gold coating on the front surface, denoted as 'eks 0030protgold900'.
The mirror's geometry is spherical, with a radius of curvature (R1) of -1000 mm, resulting in a focal length (EFL) of -500 mm. This curvature allows the mirror to focus or collimate light, making it suitable for various optical applications.
The mirror's base shape is circular, which is a common shape for optical components due to its symmetry and ease of integration into optical systems. The circular shape also allows for uniform illumination and efficient light collection.
