32-722 20 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=40mm MgF2 400-700nm
The 32-722 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is designed with a base shape of 20 mm diameter and a focal length of 40mm, making it suitable for a wide range of optical applications.
The lens is composed of two types of glass, N-BAF10 and N-SF10, both from Schott. These materials are known for their excellent optical properties, contributing to the lens's high performance. The lens is coated with Edmund Optics' standard MgF2 coating on both the front and back surfaces, ensuring optimal light transmission within the 400-700nm spectrum.
The geometry of the lens is meticulously designed, with an inner radius of 0mm, an outer radius of 0mm, and a central thickness of 8mm. The edge thickness is 7.83mm, and the lens features a curvature of r1 at 27.63mm and r2 at -17.58mm, followed by a third radius, r3, at -171.25mm. The lens also has an additional central thickness of 2mm (a), contributing to its robust design.
