AC508-400-C-ML 50.8 mm Dia. N-BAF10/N-SF6HT Mounted Achromatic Doublet; EFL=400mm 1050-1700nm
The AC508-400-C-ML is a multiplet lens, specifically an achromatic doublet, sourced from Thorlabs. This lens boasts a 50.8 mm diameter and is designed for use within the 1050-1700nm wavelength range. The lens is mounted, providing a convenient and ready-to-use solution for your optical system.
The lens's geometry is intricately designed with a range of radii and thicknesses to optimize its performance. The edge thickness is 7.8 mm, while the center thicknesses are 6.5 mm and 3 mm. The curvature radii are r1=125.6 mm, r2=-161.5 mm, and r3=376.3 mm. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF6HT, each with its unique refractive index and dispersion properties, contributing to the lens's overall achromatic performance.
The lens is coated with Thorlabs' AC1050-1700-C coating on both the front and back surfaces. This coating is specifically designed for use within the 1050-1700nm wavelength range, enhancing the lens's transmission and reducing unwanted reflections.
