This is a 31.5 mm diameter Plano-Convex lens, manufactured by Qioptiq Photonics, featuring an effective focal length (EFL) of 100mm and a spherical shape. The lens is made of N-BK7, a type of glass commonly used in optical systems due to its excellent optical properties.
The lens's geometry includes a thickness of 2.1mm at the edge and 4.5mm at the center. The inner and outer radii are 0, and the first radius of curvature (R1) is 52.33mm. This lens is uncoated, meaning it does not have any additional layers to enhance its optical properties or protect it from environmental factors.
The lens is mounted, which means it is ready to be integrated into an optical system. It is currently in stock and available for purchase on the Qioptiq Photonics website. For more detailed information, you can refer to the provided weblink.
