This is a 091-3125R-500 12.7 mm Dia. UVFS Protected Silver Plano-Concave Spherical Mirror, a high-quality optical component sourced from EKSMA Optics. The mirror has a diameter of 12.7 mm and a thickness of 6 mm at the edge, making it suitable for various optical applications.
The mirror's geometry is plano-concave, meaning it has a flat front surface and a curved back surface. The curvature of the back surface is spherical with a radius of 500 mm, and it has a focal length of -250 mm. This configuration is ideal for focusing or collimating light beams in optical systems.
The mirror is made from UVFS material, specifically UVFS mal- 1965, which is known for its excellent optical properties. It is coated with EKS 0025protsil 4000 on the front surface, a protective silver coating that enhances its reflectivity and durability.
The mirror is designed to operate at a wavelength of 400 nm, making it suitable for applications in the ultraviolet spectrum. It is currently in stock and available for immediate purchase, as indicated by its valid weblink status.
