This is a mounted plano-convex lens from Qioptiq Photonics, designed for use in precision optical applications. The lens has a diameter of 12.7 mm and a focal length of 50 mm, making it suitable for a wide range of uses. The lens is made from N-BK7, a popular optical glass from Schott, known for its excellent optical properties and versatility.
The lens features a plano-convex geometry, meaning one side is flat while the other is curved. The curvature of the lens is defined by a radius of 26.039 mm. The lens has a thickness of 2.2 mm at the edge and 3 mm at the center. The lens's coating is Qio HP Nbar Arhs-Yag, which is applied to both the front and back surfaces to reduce reflection and increase transmission.
The lens is mounted, which means it is ready to be integrated into optical systems without the need for additional mounting hardware. The weblink provided leads to the product page on Qioptiq's website, where you can find more information and check the current availability of the lens.
