This is a 091-3130R-400 12.7 mm Dia. UVFS Protected Gold Spherical Plano-Concave Mirror, designed with a thickness of 6mm and optimized for a wavelength of 900nm. The mirror is sourced from EKSMA Optics, a reputable vendor known for its high-quality optical components.
The mirror is a curved type, specifically concave, and features a base shape of a circle. It has a diameter of 12.7mm, making it suitable for applications requiring compact optical elements. The mirror's thickness at the edge is 6mm, providing structural integrity and resistance to deformation.
The mirror's geometry is spherical, with a radius of curvature (R1) of -400mm. This geometry, combined with its concave shape, results in a negative effective focal length (EFL) of -200mm. This makes the mirror ideal for focusing or collimating light in various optical systems.
The mirror is coated with EKS 0030protgold900 on the front side, a protected gold coating that enhances its reflectivity at the specified 900nm wavelength. The UVFS material ID (uvfs mal- 1965) further ensures the mirror's performance and durability.
