63-694 10 mm Dia. N-BAF10/N-SF10 Achromatic Doublet; EFL=20mm MgF2 400-700nm

The 63-694 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens, with a diameter of 10 mm, is designed for use in the visible spectrum, specifically between 400-700 nm. The lens features an effective focal length (EFL) of 20 mm, making it suitable for a wide range of optical applications.

The lens is constructed from two types of glass, N-BAF10 and N-SF10, both from Schott. These materials are chosen for their excellent optical properties, contributing to the lens's high performance. The lens is coated with MgF2, a standard coating that provides excellent anti-reflection properties, further enhancing the lens's performance.

The lens's geometry is carefully designed to optimize its optical performance. It has a thickness of 3.91 mm at the edge and 4 mm at the center, with an additional 1 mm thickness at the center's anterior side. The lens's radii are also precisely engineered, with r1 at 14.15 mm, r2 at -8.38 mm, and r3 at -71.22 mm. These parameters contribute to the lens's excellent imaging capabilities.
