This is a 095-0115R-8000 Protected Aluminium 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 300 nm and is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and high transmittance in the visible and near-infrared spectral regions.
The mirror's geometry is spherical, with a radius of curvature (R1) of -8000 mm, resulting in a focal length (EFL) of -4000 mm. This curvature and the mirror's material make it suitable for a wide range of optical applications.
The mirror is coated with EKS 0015PROTAL 3000 on the front side, a protective aluminium coating that enhances the mirror's durability and resistance to environmental factors. This coating ensures the mirror maintains its optical properties over time, making it a reliable choice for various applications.
