This is a G312329329 Plano-Convex Lens, a high-quality optical component sourced from Qioptiq Photonics. The lens has a circular base shape and a diameter of 12.5 mm, making it suitable for a wide range of optical applications. The lens's geometry includes a thickness of 1.4 mm at the edge and 3.5 mm at the center, with an effective focal length (EFL) of 20 mm at a wavelength of 1064 nm.
The lens is made of N-BK7, a popular glass type in the optical industry known for its excellent optical properties. The front and back surfaces of the lens are coated with "qio hp nbar arhs-yag", a specialized coating that enhances the lens's performance in specific wavelength ranges.
The lens's shape is spherical, a common choice for its simplicity and versatility. The inner and outer radii are 0, indicating a plano-convex lens, where one surface is flat, and the other is curved. The radius of curvature (R1) of the curved surface is 10.44 mm.
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.
