10mm Diameter x 25mm FL Double-Convex Lens with MgF2 Coating from Edmund Optics
This item is a 10mm diameter x 25mm focal length double-convex lens, coated with MgF2 on both sides. It is sourced from the reputable optical components vendor, Edmund Optics. The lens is designed for use within the wavelength range of 400-700nm, making it suitable for a wide range of optical applications.
The lens geometry features a diameter of 10mm, a thickness at the edge of 1.51mm, and a center thickness of 2.5mm. The effective focal length (EFL) is 25mm, and the radii of curvature are 25.41mm for the first surface and -25.41mm for the second surface. The back focal length (BFL) is 24.16mm, and both the inner and outer radii are 0mm.
The lens material is n-BK7 Schott, a common and reliable material in the optical industry due to its excellent optical properties and chemical durability. The MgF2 coating on both the front and back surfaces of the lens is a standard coating that provides high transmission and low reflectance across the specified wavelength range.
