47-397 50.0mm Dia. x 500.0mm FL; VIS-NIR Coated; Plano-Convex Lens VIS-NIR 400-1000nm
The 47-397 is a Plano-Convex lens, a type of spherical lens, with a diameter of 50.0mm and a focal length of 500.0mm. 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 catering to wavelengths between 400 and 1000nm.
The lens's geometry is characterized by a thickness of 3.79mm at the edge and 5.0mm at the center. The front surface has a radius of curvature of 258.4mm, and the back focal length is 496.7mm. The lens is made from n-BK7 Schott, a popular optical glass due to its excellent optical properties and versatility.
The 47-397 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 within the visible to near-infrared spectrum, reducing surface reflections and improving transmission.
