6mm Dia. x 24mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
This 6mm Dia. x 24mm FL; VIS-NIR Coated; UV Double-Convex Lens is a high-quality optical component sourced from Edmund Optics. It is specifically designed for use in the visible to near-infrared spectrum, covering the wavelength range of 400-1000nm.
The lens features a spherical design, with a base shape of a circle. The geometry of the lens includes a diameter of 6mm, a thickness at the edge of 1.58mm, and a thickness at the center of 2mm. The effective focal length (EFL) of the lens is 24mm, and the back focal length (BFL) is 23.31mm. The first and second radii of curvature (R1 and R2) are 21.69mm and -21.69mm respectively.
The lens is made from fused silica, identified as mal-1965 in the material ID. This material is known for its excellent optical properties, making it suitable for a wide range of applications.
The lens is coated with a VIS-NIR coating, denoted as edm visnir0sp2002000, on both the front and back surfaces. This coating enhances the lens's performance in the visible to near-infrared spectrum, providing improved transmission and reduced reflection.
