88-742 25.4mm Dia. x 76.2mm FL; VIS-EXT Coated Plano-Convex Lens VIS-EXT 350-700nm
The 88-742 is a Plano-Convex lens, a type of spherical lens, sourced from Edmund Optics. This lens boasts a diameter of 25.4mm and a focal length of 76.2mm, making it suitable for a wide range of optical applications. The lens is made from n-BK7 Schott, a high-quality optical glass known for its excellent transparency and low dispersion.
The lens features a front and back coating of EDM VIS EXT, a broadband anti-reflection coating designed for use in the visible spectrum, specifically between 350-700nm. This coating significantly reduces surface reflections, thereby improving transmission and enhancing the overall performance of the lens.
The geometry of the lens includes a thickness of 1.9mm at the edge and 4mm at the center. The inner radius is 0mm, and the outer radius is also 0mm, indicating a flat surface on the uncoated side of the lens. The lens's effective focal length (EFL) is 76.2mm, and the back focal length (BFL) is 73.56mm.
