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 200 mm at a wavelength of 1064 nm. The lens is made from N-BK7 glass, a popular choice for its high homogeneity and low auto-fluorescence.
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 102.92 mm. The lens has a thickness of 2.8 mm at the edge and 3 mm at the center. The lens is mounted, providing convenience and ease of use in optical systems.
The lens is coated with Qio HP Nbar ARHS-YAG on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission, particularly at the 1064 nm wavelength. The coating also provides protection against environmental factors, ensuring the longevity and performance of the lens.
