47-851 4.0mm Dia. x 6.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-851 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens has a diameter of 4.0mm and a focal length of 6.0mm, making it a compact and efficient optical component. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a VIS-NIR coating, specifically edm visnir0sp2002000, on both the front and back surfaces. This coating enhances the lens's performance in the visible and near-infrared spectrum, which spans from 400 to 1000nm. The coating reduces surface reflections, thereby increasing the amount of light transmitted through the lens. This makes the lens ideal for applications that require high transmission and low loss, such as imaging systems, beam shaping, and laser applications.
The lens's geometry includes a thickness of 1.53mm at the edge and 2.26mm at the center. The front surface has a radius of curvature of 3.11mm, and the back focal length is 4.51mm. The lens's base shape is circular, and it does not have any inner or outer radius, indicating a uniform thickness across the lens.
