88-668 10.0mm Dia. x 50.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm

The 88-668 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 10.0mm 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. This material ensures that the lens provides clear, distortion-free images, making it suitable for use in imaging systems, beam shaping, and other applications where high-quality optical performance is required.

The lens features a VIS-EXT coating on both the front and back surfaces. This coating is designed to extend the lens's usable wavelength range from 350 to 700nm, making it suitable for use in a wide range of applications, including those that involve ultraviolet and visible light. The VIS-EXT coating also helps to reduce surface reflections, improving the overall light transmission and enhancing the lens's performance in high-light applications.

The geometry of the lens includes a thickness of 2.51mm at the edge and 3.0mm at the center. The lens's inner and outer radii are both 0, indicating a flat surface on the side opposite the convex surface. The lens's radius of curvature (R1) is 25.84mm, and its back focal length (BFL) is 48.02mm.
