This is a mounted plano-convex lens from Qioptiq Photonics, specifically designed for use in optical systems requiring a focal length of 500mm at a wavelength of 1064nm. The lens has a diameter of 31.5mm and a thickness of 2mm at the edge, increasing to 2.5mm at the center.
The lens is made from N-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and wide transparency range. This lens features a spherical shape, with a radius of curvature of 259.476mm on the curved (convex) side. The flat side of the lens has no radius of curvature, as indicated by the "Plano" in its name.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This coating is designed to reduce reflection and increase transmission at the specified wavelength, enhancing the performance of your optical system.
The lens is mounted, making it ready for immediate use in your optical setup. According to the vendor's information, this item is currently in stock and can be purchased directly from the Qioptiq Photonics website.
