38-484 6.0mm Dia. x 20mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
This is a 6.0mm diameter, plano-convex lens with a focal length of 20mm, designed for use in the visible to near-infrared spectrum (400-1000nm). The lens is sourced from Edmund Optics, a leading provider of optical components.
The lens is made from n-BK7 Schott glass, a popular material for optical elements due to its excellent optical properties and high Abbe number. The plano-convex geometry, where one side is flat and the other is curved, is a common design for lenses, providing a wide range of focusing capabilities.
The lens features a front and back coating of edm visnir0sp2002000, a broadband anti-reflection coating designed for use in the visible to near-infrared spectrum. This coating reduces surface reflections, improving transmission and reducing unwanted optical artifacts.
The lens has a center thickness of 1.45mm and an edge thickness of 1.01mm, providing a robust and durable structure. The inner and outer radii are both 0mm, indicating a simple, spherical curvature. The effective focal length (EFL) is 20mm, a common value for this type of lens.
