88-761 50.0mm Dia. x 75.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-761 is a Plano-Convex lens, a type of spherical lens, with a diameter of 50.0mm and a focal length of 75.0mm. This lens is sourced from Edmund Optics, a renowned vendor in the optical industry. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low auto-fluorescence.
The lens features a VIS-EXT coating on both the front and back surfaces. This coating, specific to the visual spectrum (350-700nm), enhances the lens's transmission in this range, reducing surface reflections and improving overall light transmission. The edge thickness of the lens is 1.86mm, while the center thickness is 11mm, providing a robust and durable structure.
The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, indicating a uniform curvature. The effective focal length (EFL) is 75.0mm, and the back focal length (BFL) is 67.75mm. The radius of curvature (R1) is 38.76mm.
