49-761 12.7 mm Dia. N-SSK8/N-SF56 Achromatic Doublet; EFL=31.75mm MgF2 400-700nm

The 49-761 is a high-quality achromatic doublet lens, sourced from the renowned optical vendor, Edmund Optics. This lens is designed with a base shape of a circular multiplet, featuring a diameter of 12.7 mm and a focal length of 31.75 mm, making it suitable for a wide range of optical applications.

The lens is constructed from two types of materials, N-SSK8 and N-SF56, both from Schott, ensuring durability and high-performance. The geometry of the lens is meticulously designed with an inner radius of 0, an outer radius of 0, and a thickness at the edge of 4.45 mm. The center thickness is 4 mm, while the center thickness 'a' is 1.75 mm, providing a balanced structure for optimal optical performance.

The 49-761 lens features a coating of MgF2 on both the front and back surfaces, following the standard curve from Edmund Optics. This coating enhances the lens's light transmission capabilities within the spectral range of 400-700 nm. The lens's coating and material composition contribute to its overall achromatic performance, minimizing chromatic aberration and delivering clear, sharp images.
