This is the G063102000 31.5 mm Dia. N-BAK4 Mounted Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens, which has an effective focal length (EFL) of 50mm, is designed for use in a variety of optical systems and applications.
The lens is spherical in shape, with a base shape of circular. It has a diameter of 31.5 mm and a thickness at the edge of 2 mm, while the thickness at the center is 6.7 mm. The lens is made from N-BAK4 Schott, a type of optical glass known for its excellent optical properties.
The lens is uncoated, meaning it does not have any additional layers applied to its surface to alter its optical properties. This can be beneficial in certain applications where a natural lens surface is preferred.
The lens is mounted, making it ready for immediate use in optical systems. It is currently in stock and available for purchase through the Qioptiq Photonics website. For more information, please refer to the provided weblink.
