89-133 6mm Dia. x 24mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
This is a 6mm diameter, double-convex lens with a focal length of 24mm, sourced from Edmund Optics. The lens is made from the high-quality material n-BK7 Schott, a borosilicate crown glass known for its excellent optical properties. The lens features a VIS-EXT coating on both the front and back surfaces, designed to enhance transmission within the visible spectrum, specifically between 350-700nm.
The lens has a center thickness of 2.6mm and an edge thickness of 2.23mm, providing a robust structure while maintaining a compact form factor. The inner and outer radii are not specified, indicating that the lens has a uniform curvature throughout. The effective focal length (EFL) is 24mm, and the back focal length (BFL) is 23.13mm, which is the distance from the back surface of the lens to the focal point.
This lens is a versatile choice for applications that require a compact, high-performance optical component within the visible light spectrum. Its double-convex design and VIS-EXT coating make it suitable for use in various settings, including imaging systems, beam shaping, and other optical applications.
