AC508-400-B-ML 50.8 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=400mm 650-1050nm
The AC508-400-B-ML is a mounted achromatic doublet lens, sourced from Thorlabs, designed for use within the 650-1050nm spectral range. This lens boasts a 50.8 mm diameter, making it suitable for a wide range of applications. The lens features a multilayer coating, specifically the THo AC650-1050-B, on both the front and back surfaces, enhancing its performance within the specified spectral range.
The lens's geometry is intricately designed with three radii of curvature (r1, r2, and r3) and two centers of thickness, contributing to its superior optical performance. The first center of thickness measures 4.5 mm, while the second is 2.6 mm, and the edge thickness is 5.6 mm. The lens is constructed from two types of Schott glass, N-LAK22 and N-SF6HT, which are renowned for their optical qualities.
This lens is part of the Multiplets subtype, which refers to a compound lens made up of multiple elements. The base shape is circular, and the lens is mounted, providing users with a ready-to-use optical component.
