The 38-520 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. It boasts a diameter of 15.0mm and a focal length of 50.0mm, making it a versatile choice for various optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of edm visnir0sp2002000, a VIS-NIR coating suitable for use in the visible and near-infrared spectrum, specifically designed for applications within the 400-1000nm range. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving overall system efficiency.
The geometry of the lens includes a thickness of 1.39mm at the edge and 2.5mm at the center. The inner and outer radii are both zero, and the lens has a base shape of circular. The front surface has a radius of curvature of 25.84mm, and the back focal length is 48.35mm.
