The 48-252 is a Plano-Convex Lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 50.0mm and a focal length of 500.0mm, 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. This material makes the lens suitable for use in a wide range of wavelengths, specifically from 425 to 675nm.
The 48-252 features a front and back coating of EDM VIS-0 STD CURVE, a broadband anti-reflection coating designed for use in the visible spectrum. This coating enhances the lens's performance by reducing surface reflections, thereby increasing transmission and improving image quality.
The lens's geometry includes a thickness edge of 3.79mm and a thickness center of 5mm. The inner and outer radii are both zero, indicating a plano surface on one side and a curved surface on the other. The radius of curvature (R1) is 258.4mm, and the back focal length (BFL) is 496.7mm.
