88-718 20.0mm Dia. x 100.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-718 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 20.0mm and a focal length of 100.0mm, making it a versatile choice for various optical applications.
The lens is made from n-bk7 schott, a popular optical glass due to its excellent optical properties and relatively low cost. The lens's geometry includes a thickness of 3.32mm at the edge and 4.3mm at the center, with an effective focal length (EFL) of 100.0mm. The radius of curvature (R1) is 51.68mm, and the back focal length (BFL) is 97.13mm.
The 88-718 lens features VIS-EXT coating on both the front and back surfaces. This coating, specific to Edmund Optics, is designed to enhance transmission in the visible spectrum, specifically between 350-700nm. This coating aids in reducing surface reflections and improving overall system performance.
Please note that the lens's inner and outer radii are both 0mm, indicating a flat surface on the uncoated side. This feature can be beneficial in certain applications where a flat surface is required.
