34-192 40mm Dia. x 100mm FL; VIS-EXT Coated; Double-Convex Lens VIS-EXT 350-700nm
This is a high-quality double-convex lens from the renowned optical components manufacturer, Edmund Optics. The lens, with the product code 34-192, features a 40mm diameter and a focal length of 100mm, making it suitable for a wide range of applications.
The lens is made from Schott's n-BK7 glass, a popular material for optical elements due to its excellent optical properties and chemical resistance. The base shape of the lens is circular, and it has a double-convex geometry, meaning it has two spherical surfaces that curve outwards. This design is often used to increase the optical power of a lens or to reduce spherical aberration.
The lens's geometry includes a thickness of 4.04mm at the edge and 8mm at the center. The back focal length (BFL) is 97.33mm, and the effective focal length (EFL) is 100mm. The first radius of curvature (R1) is 101.98mm, and the second radius of curvature (R2) is -101.98mm. The inner and outer radii are both 0mm.
The lens is coated with Edmund Optics' VIS-EXT coating on both the front and back surfaces. This coating is designed to extend the wavelength range of the lens to cover the visible spectrum (350-700nm), making it ideal for applications that require broadband light transmission.
