38-520-INK 15.0mm Dia. x 50.0mm FL; VIS-NIR; Inked; Plano-Convex Lens VIS-NIR 400-1000nm
The 38-520-INK is a plano-convex lens, a type of spherical lens, sourced from Edmund Optics. This lens, with a diameter of 15.0mm and a focal length of 50.0mm, is designed for use in the visible to near-infrared spectrum, specifically between 400-1000nm.
The lens's geometry is characterized by its edge thickness of 1.39mm and center thickness of 2.5mm. The front surface has a radius of curvature of 25.84mm, and the back focal length is 48.35mm. The lens is made of N-BK7 Schott, a popular optical glass known for its excellent optical properties and versatility.
The 38-520-INK lens features a VIS-NIR coating, denoted as 'edm visnir0sp2002000' on both the front and back surfaces. This coating is designed to enhance the lens's performance in the visible to near-infrared spectrum, improving transmission and reducing reflection.
