38-552-INK 35.0mm Dia. x 50.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm

The 38-552-INK is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. It boasts a diameter of 35.0mm and a focal length of 50.0mm, making it suitable for a wide range of applications. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.

The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating designed for use in the visible and near-infrared regions of the spectrum, specifically from 400 to 1000nm. This coating enhances the lens's performance by reducing surface reflections and increasing transmission, making it ideal for applications that require high light transmission and clarity.

The geometry of the lens includes an inner radius of 0mm and an outer radius of 0mm, with a thickness at the edge of 1.67mm and a thickness at the center of 8.5mm. The lens's base shape is circular, and its shape is spherical, which is a common choice for applications that require minimal optical aberration.

The lens's EFL (Effective Focal Length) is 50mm, and its R1 (Radius of Curvature) is 25.84mm. The BFL (Back Focal Length) is 44.4mm. These parameters are crucial in determining the lens's performance in a specific optical system.
