63-794 12mm Dia. x 25mm FL VIS-NIR Coated; UV Plano-Convex Lens VIS-NIR 400-1000nm
The 63-794 is a UV Plano-Convex Lens, 12mm in diameter and 25mm in focal length, designed for use in the visible to near-infrared spectrum (VIS-NIR), specifically covering the 400-1000nm range. This lens is sourced from the reputable optical vendor, Edmund Optics.
The lens is spherical in shape, with a base shape of a circle. The geometry of the lens includes a 12mm diameter, a 2.22mm edge thickness, and a 3.92mm center thickness. The effective focal length (EFL) is 25mm, and the front radius (R1) is 11.46mm. The back focal length (BFL) is 22.31mm, and the lens does not have any inner or outer radius.
The lens is made from fused silica, identified as mal-1965 in the material ID. This material is known for its excellent transmission properties in the VIS-NIR range.
The lens features a coating on both the front and back surfaces. The coating is edm visnir0sp2002000, which is a broadband anti-reflection coating designed for use in the VIS-NIR range. This coating helps to reduce surface reflections and increase transmission, enhancing the performance of the lens in its designated spectrum.
