G063029525 22.4 mm Dia. N-BK7 Mounted Double-Convex Lens; EFL=200mm 725-1050nm
This is a mounted double-convex lens from Qioptiq Photonics, designed for use within the wavelength range of 725-1050nm. The lens has a base shape of a circle and is constructed from N-BK7 Schott glass, a popular material for its high refractive index and low dispersion.
The lens has a diameter of 22.4mm and a thickness of 2.4mm at the edge, with a center thickness of 3mm. The effective focal length (EFL) of this lens is 200mm. The front and back surfaces of the lens have a broadband anti-reflection coating (BBAR), specifically the Qio Bbar Arb2nirnbk7 coating, which enhances transmission and reduces surface reflections.
The lens features two radii of curvature: the first (R1) is 209.83mm, and the second (R2) is -209.83mm. The lens does not have an inner radius, and the outer radius is also 0mm. This specific lens is mounted, making it ready for immediate use in optical systems.
