45-865 6mm Dia. x 36mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
The 45-865 is a high-quality double-convex lens, boasting a 6mm diameter and a 36mm focal length. This lens is sourced from the reputable optical vendor, Edmund Optics, and is available for immediate purchase, as indicated by its "in stock" status on the company's website.
The lens is constructed from Schott's n-BK7 glass, a popular choice in the optical industry due to its excellent optical properties and versatility. The lens's geometry is characterized by a 36.87mm radius of curvature on the first surface and a -36.87mm radius on the second surface, creating a symmetrical, double-convex design. The lens has a central thickness of 2mm and an edge thickness of 1.76mm, providing a robust structure while maintaining a sleek profile.
The 45-865 lens features a broad spectral range, with a coating optimized for the visible (VIS) and near-infrared (NIR) spectrum, specifically between 400 and 1000nm. This coating, denoted as 'edm visnir0sp2002000', is applied to both the front and back surfaces of the lens, enhancing its transmission capabilities and reducing unwanted reflections.
