49-255 6mm Dia. x 9mm; UV-VIS Coated; UV Double-Convex Lens UV-VIS 250-700nm
The 49-255 is a UV-VIS coated, UV double-convex lens, boasting a diameter of 6mm and a thickness of 9mm. This lens is sourced from the reputable vendor, Edmund Optics, and is currently in stock. The lens is designed with a spherical shape, featuring a base shape of a circle, and is part of the Spherical Lens (Convex-Convex) subtype.
The lens's geometry is meticulously crafted, with an edge thickness of 1.5mm and a center thickness of 2.7mm. The effective focal length (EFL) is 9mm, while the first and second radii (R1 and R2) are 7.8mm and -7.8mm respectively. The back focal length (BFL) is 8.02mm, with both inner and outer radii being 0mm.
The lens is constructed from the material fused sil mal-1965, and it is optimized for a wavelength of 587.6nm. The lens is coated with a standard UV-VIS coating on both the front and back, adhering to the Edmund Optics UV-VIS standard curve. This coating enhances the lens's performance within the UV-VIS spectrum, specifically between 250-700nm.
