This is the G312244322 model from Qioptiq Photonics, a 50 mm diameter Plano-Convex lens made of UVFS material. The lens has a focal length (EFL) of 200mm and is designed to work within the wavelength range of 450-700nm.
The lens geometry is characterized by its spherical shape, with a radius of curvature (R1) of 100mm. The edge thickness is 1.9mm, while the center thickness is 5.1mm. The lens does not have an inner radius, and the outer radius is also 0. This suggests a simple, straightforward design that is easy to integrate into various optical systems.
The lens is coated with Qio Bbar Arb2visnbk7 on both the front and back surfaces. This coating is specifically designed to enhance the lens' performance within its specified wavelength range.
The lens is currently in stock and available for purchase on the Qioptiq Photonics website. For more detailed information, you can refer to the provided weblink.
