This is a 092-3115R-400 UVFS Protected Aluminium Spherical Plano-Concave Mirror, sourced from the reputable vendor, EKSMA Optics. The mirror has a diameter of 25.4 mm and a thickness of 6 mm at the edge, making it a robust and stable optical component.
The mirror's geometry is spherical, with a radius of curvature (R1) of -400 mm, which results in a focal length (EFL) of -200 mm. This negative focal length indicates that the mirror is a concave mirror, which is commonly used to converge light rays.
The mirror is made from UVFS material, identified as UVFS Mal- 1965 in the item data. This material is specifically designed for use in the ultraviolet region of the spectrum, making this mirror suitable for applications involving UV light.
The mirror is coated with EKS 0015PROTAL 3000 on the front surface. This coating is a protective aluminium coating, which enhances the mirror's durability and resistance to environmental factors. The coating is designed for use at a wavelength of 300 nm, further emphasizing the mirror's suitability for UV applications.
