The 33-367-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 25.0mm, is designed for use in the visible to near-infrared (VIS-NIR) spectrum, specifically catering to wavelengths of 587.6nm.
The lens features a front and back coating of edm visnir0sp2002000, which is an in-house coating developed by Edmund Optics. This coating enhances the lens's performance in the VIS-NIR spectrum, providing improved transmission and reduced reflection.
The lens has a thickness of 2.82mm at the edge and 3.2mm at the center. The effective focal length (EFL) is 400mm, and the radius of curvature (R1) is 206.72mm. The back focal length (BFL) is 397.89mm, and the lens does not have an inner or outer radius.
This lens is made of n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence. The lens is available in stock, as indicated by the weblink status, making it a reliable choice for immediate optical needs.
