AC508-1000-C 50.8 mm Dia. N-SF5/N-SF6 Unmounted Achromatic Doublet; EFL=1010mm 1050-1700nm

The AC508-1000-C is a high-quality achromatic doublet lens, featuring a 50.8 mm diameter and a focal length of 1010mm, specifically designed for use within the 1050-1700nm wavelength range. This lens is sourced from the renowned optical component manufacturer, Thorlabs, and boasts an impressive catalog number of AC508-1000-C.

This unmounted doublet lens is composed of two distinct materials, N-SF5 and N-SF6, both from the Schott glass catalog. The lens's complex geometry includes an edge thickness of 8.1mm, an inner radius of 0mm, and an outer radius of 0mm. The curvature radii are r1=173mm, r2=-234.3mm, and r3=336mm, while the center thicknesses are 6mm and 3mm for the first and second surfaces, respectively.

The lens features a proprietary Thorlabs anti-reflection coating, denoted as tho ac1050-1700-c, on both the front and back surfaces. This coating is specifically designed to enhance transmission and minimize reflection within the 1050-1700nm wavelength range.

The AC508-1000-C is a multiplet lens, characterized by its multiple glass elements arranged in a specific configuration to achieve superior optical performance. This lens type is commonly used in applications requiring high-precision imaging and beam shaping, such as microscopy, interferometry, and laser systems.
