091-0115R-50 12.7 mm Dia. N-BK7 Protected Aluminium Spherical Plano-Concave Mirror; t=6mm 300nm

This 091-0115R-50 mirror is a curved mirror with a concave base shape and a spherical geometry, featuring a diameter of 12.7 mm and a thickness edge of 6 mm. The mirror is designed with a effective focal length (EFL) of -25 mm and a radius of curvature (R1) of -50 mm, making it suitable for a wide range of optical applications.

The mirror is made from N-BK7 Schott, a popular optical glass known for its excellent optical properties, including high homogeneity, low auto-fluorescence, and superior transmittance in the visible and near-infrared spectral ranges. This material is widely used in various optical systems, such as beam expanders, laser resonators, and interferometers.

The mirror is coated with EKS 0015PROTAL 3000, a protected aluminium coating that provides high reflectivity in the ultraviolet (UV) region, specifically at 300 nm. This coating is designed to protect the aluminium layer from oxidation and environmental degradation, ensuring long-term stability and durability.

The mirror is offered by EKSMA Optics, a leading vendor of optical components, and is currently in stock, as indicated by its valid weblink status. For more information about this product, please refer to the vendor's website.
