G312403400 31.5 mm Dia. N-BK7 Plano-Convex Lens; EFL=80mm
This is a Plano-Convex lens, type of spherical lens, with a diameter of 31.5 mm, sourced from Qioptiq Photonics. The lens has a front side that is flat (plano) and a back side that is curved (convex). The lens's thickness at the edge is 1.9 mm, while at the center it is 5 mm, providing a robust structure.
The Effective Focal Length (EFL) of this lens is 80 mm, which is the distance from the lens's center to the focal point when the lens is placed in a converging position. The lens's front and back surfaces are coated with Qio Silver RAGV 45, enhancing its performance in specific wavelengths.
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 inner and outer radii are 0, indicating a sharp transition from the flat to the curved surface.
This lens is currently in stock and available for purchase on the Qioptiq Photonics website. The link to the product page is provided for your convenience.
