88-719 20.0mm Dia. x 150.0mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-719 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 150.0mm, 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 delivers sharp, clear images with minimal chromatic aberration.
The 88-719 features a VIS-EXT coating on both the front and back surfaces. This coating enhances the lens's performance in the visible spectrum, specifically between 350-700nm. It improves light transmission, reduces surface reflections, and protects the lens from environmental hazards, thereby increasing its durability and longevity.
The geometry of the lens is carefully designed to optimize its optical performance. The edge thickness is 2.35mm, while the center thickness is 3mm. The lens's effective focal length (EFL) is 150.0mm, and its back focal length (BFL) is 148.02mm. The radius of curvature (R1) is 77.52mm.
