This is a 095-3215R+200 protected aluminium spherical plano-convex mirror, sourced from EKSMA Optics. The mirror has a diameter of 50.8 mm and a thickness of 10 mm at the center. It is designed for use with a wavelength of 300 nm and features a UVFS protected aluminium coating on the front surface, identified as 'eks 0015protal 3000'.
The mirror's geometry is spherical, with a radius of curvature (R1) of 200 mm, resulting in an effective focal length (EFL) of 100 mm. This curvature gives the mirror a convex shape, which can be used to diverge or focus light, depending on the application.
The mirror is available for purchase directly from the EKSMA Optics website, where it is currently listed as in stock. For more detailed information, including technical specifications and purchasing options, please refer to the provided weblink.
