This is the G063353331 model from Qioptiq Photonics, a 22.4 mm diameter Plano-Concave Lens with a mounted UVFS. The lens is designed with a negative focal length (EFL) of -50mm, making it suitable for applications that require light convergence.
The lens is made of UVFS material with the Mal-1965 index, ensuring high transmittance in the ultraviolet spectrum, specifically at 355nm. The lens is coated on both sides with Qio AL RALVIS AOI 45, providing anti-reflection properties and enhancing its light transmission capabilities.
The lens geometry features a center thickness of 1.5mm, with a spherical shape determined by a radius of curvature (R1) of -25.483mm on the concave side. The lens does not have an inner or outer radius, indicating a uniform curvature across its surface.
The lens is mounted, suggesting it is ready for immediate use in optical systems. The vendor, Qioptiq Photonics, provides a valid web link for this item, indicating its availability in their inventory.
