45-877 12mm Dia. x 48mm FL; VIS-NIR Coated; Double-Convex Lens VIS-NIR 400-1000nm

This is a 12mm diameter, double-convex lens with a focal length of 48mm, 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.

The lens is made of the high-quality material, n-BK7 Schott, which is known for its excellent optical properties and durability. The front and back surfaces of the lens are coated with the advanced EDM VIS-NIR 0SP 200-2000 coating, which enhances its performance in the VIS-NIR spectrum (400-1000nm).

The lens's geometry is meticulously designed, with an edge thickness of 2mm and a center thickness of 2.74mm. The first radius of curvature (R1) is 49.14mm, while the second radius (R2) is -49.14mm, indicating a double-convex shape. The back focal length (BFL) is 47.09mm, and both the inner and outer radii are 0mm.
