The 32-307 is a high-quality achromatic doublet lens from Edmund Optics, designed with a 6.25 mm diameter and a focal length of 35mm. This lens is a multiplet, meaning it is composed of multiple optical elements to achieve superior performance.
The lens is constructed from two types of glass, N-BK7 and N-SF5, both from Schott. These materials are known for their excellent optical properties, contributing to the lens's high-performance characteristics. The lens features a standard MgF2 coating on both the front and back surfaces, which enhances its transmission capabilities within the 400-700nm spectrum.
The geometry of the lens is carefully designed to optimize its optical performance. The inner and outer radii are zero, indicating a symmetrical design. The first radius of curvature (r1) is 23.14, while the second radius (r2) is -14.51, and the third radius (r3) is -38.86. The edge thickness is 2.86mm, and the center thickness is 2.3mm, with a center thickness 'a' of 0.9mm.
