This is a 095-3125R-200 protected silver plano-concave spherical 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 have an effective focal length (EFL) of -100 mm, making it a concave mirror. The mirror's radius of curvature (R1) is -200 mm.
The mirror is made of UVFS material, specifically UVFS mal- 1965, and is coated with EKS 0025protsil 4000 on the front side. This coating is designed to protect the silver mirror and optimize its performance at a wavelength of 400 nm.
The mirror's base shape is circular, and its geometry is spherical. It is in stock and available for immediate purchase. For more information, please refer to the vendor's website at https://eksmaoptics.com/optical-components/metallic-mirrors/protected-silver-mirrors/.
