31-858 3mm Dia. x 3mm FL; MgF2 Coated; Double-Convex Lens MgF2 400-700nm
The 31-858 is a high-quality double-convex lens, boasting a 3mm diameter and a focal length of 3mm. This lens is sourced from the renowned optical vendor, Edmund Optics, and is currently in stock. The lens is made from n-sf5 schott material, ensuring durability and reliability.
The lens features a standard MgF2 coating on both the front and back surfaces, providing excellent transmission characteristics within the 400-700nm wavelength range. This coating enhances the lens's performance by reducing reflection and increasing transmittance, making it an ideal choice for various applications.
The geometry of the lens is meticulously designed, with an edge thickness of 1.64mm and a center thickness of 2.3mm. The inner and outer radii are 0mm, and the effective focal length (EFL) is 3mm. The first and second radii of curvature are 3.5mm and -3.5mm, respectively, contributing to the lens's superior optical performance.
