This is a mounted plano-convex lens, type G063046400, with a diameter of 22.4 mm, sourced from Qioptiq Photonics. The lens is made of N-BK7, a popular optical glass from Schott, and features a front coating of Qio Silver RAGV 45 and a back coating of the same.
The lens's geometry is characterized by its plano-convex shape, meaning one side is flat while the other is curved. The curved side has a radius of 41.867 mm, and the lens has an effective focal length (EFL) of 80 mm. The edge thickness of the lens is 1.9 mm, while the center thickness is 3.5 mm.
This lens is designed to operate at a wavelength of 588 nm. It is currently in stock and available for purchase on the Qioptiq Photonics website. The link to the product page is provided for your convenience.
Please note that this lens is spherical in shape, which means it has the same curvature throughout its surface. This is a common type of lens used in various optical applications due to its simplicity and versatility.
