This is the G063352000 model from Qioptiq Photonics, a 22.4 mm diameter Plano-Concave Lens with a UVFS mounted fused silica. The lens is designed with a negative focal length (EFL) of -40mm, making it suitable for applications that require light convergence.
The lens's geometry is characterized by its spherical shape, with a center thickness of 1.5mm. The inner and outer radii are both zero, indicating a plano-concave design. The curvature radius (R1) is -20.097mm, contributing to the lens's negative focal length.
The lens is made from UVFS material, specifically identified as "UVFS mal- 1965". This material is suitable for use with a wavelength of 355nm. The lens is uncoated, which means it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
