AC254-030-C-ML 25.4 mm Dia. N-BAF10/N-SF6HT Mounted Achromatic Doublet; EFL=30mm 1050-1700nm
The AC254-030-C-ML is a multiplet lens, specifically an achromatic doublet, sourced from Thorlabs. This lens boasts a 25.4 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 center thickness of 13mm for the first center and 1.8mm for the second. The radii of curvature are -15.2mm, -71.1mm, and 21.1mm, contributing to the lens's unique optical properties. The edge thickness is 9.4mm, and both the inner and outer radii are 0mm, indicating a flat surface.
The lens is composed of two materials: N-BAF10 and N-SF6HT, both from Schott. These materials are chosen for their specific refractive indices and dispersion properties, which contribute to the lens's achromatic design. The lens is coated with THo AC1050-1700-C on both the front and back surfaces, enhancing its performance within the specified wavelength range.
