6mm Dia. x 9mm FL; VIS-NIR Coated; UV Double-Convex Lens VIS-NIR 400-1000nm
This 6mm Dia. x 9mm FL; VIS-NIR Coated; UV Double-Convex Lens, sourced from Edmund Optics, is a high-quality optical component designed for use in the visible to near-infrared spectrum, specifically covering the 400-1000nm range.
The lens is spherical in shape, featuring a double-convex design with a 6mm diameter and a 9mm focal length. The base shape is circular, and the lens has a center thickness of 2.7mm and an edge thickness of 1.5mm. The effective focal length (EFL) is 9mm, and the radii of curvature are 7.8mm for the first surface and -7.8mm for the second surface. The back focal length (BFL) is 8.02mm.
The lens is made from fused silica, identified as fused sil mal-1965 in the material database. This material is known for its excellent optical properties, making it suitable for a wide range of applications.
The lens features a VIS-NIR coating on both the front and back surfaces, identified as edm visnir0sp2002000. This coating is designed to enhance the lens' performance in the visible to near-infrared spectrum, reducing reflection and increasing transmission.
