38-484-INK 6.0mm Dia. x 20mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-484-INK is a plano-convex lens, a type of spherical lens, with a diameter of 6.0mm and a focal length of 20mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is designed for use within the visible to near-infrared spectrum, specifically between 400-1000nm, making it suitable for a wide range of optical applications.
The lens features a plano-convex geometry, meaning one side is flat (plano) and the other side is curved (convex). The curvature of the lens is defined by a radius of 10.34mm on the curved side. The lens has a central thickness of 1.45mm and an edge thickness of 1.01mm, providing a robust structure while maintaining a compact form factor.
The lens is made from N-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility. The lens is coated with a VIS-NIR coating, specifically the edm visnir0sp2002000 coating, on both the front and back surfaces. This coating enhances the lens's performance within the specified wavelength range, improving transmission and reducing reflection.
