45-872 12mm Dia. x 12mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm
This is a 12mm diameter, double-convex lens, designed for use in the visible to near-infrared spectrum (VIS-NIR), specifically catering to the wavelength of 587.6nm. The lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock, as indicated by its weblink status.
The lens features a focal length of 12mm and a thickness of 1.41mm at the edge, with a center thickness of 3.85mm. The front and back surfaces of the lens are coated with a VIS-NIR coating, specifically the 'edm visnir0sp2002000' coating, which enhances its performance in the specified wavelength range.
The lens's geometry includes an inner radius of 0 and an outer radius of 0, with radii of curvature of 15.34mm for the first surface and -15.34mm for the second surface. The back focal length (BFL) of the lens is 10.79mm.
The lens is made of n-SF5 Schott, a high-quality optical material known for its excellent transmission properties in the VIS-NIR range. This lens is a spherical lens, meaning it has a spherical surface, which is a common type of lens due to its ease of manufacturing and versatile applications.
