AC254-500-C-ML 25.4 mm Dia. SF2/N-SF6HT Mounted Achromatic Doublet; EFL=500mm 1050-1700nm
The AC254-500-C-ML is a multiplet lens with a 25.4 mm diameter, specifically designed for use in the infrared spectrum, between 1050 and 1700 nanometers. This lens is manufactured by Thorlabs, a leading vendor in the field of optical components.
The lens features a complex geometry, with a center thickness of 3.5 mm and 2 mm at its edges. The curvature of the lens is defined by three radii: r1 at 87.9 mm, r2 at -115.5 mm, and r3 at 194.5 mm. The lens is mounted, ensuring ease of integration into optical systems.
The lens is composed of two types of glass: SF2 from Schott and N-SF6HT from Schott. These materials were chosen for their specific optical properties, which contribute to the lens's overall performance. The lens is coated with a broadband anti-reflection coating (tho ac1050-1700-c) on both the front and back surfaces, further enhancing its performance in the infrared spectrum.
This lens is part of Thorlabs' extensive catalog and is currently in stock, indicating its popularity and versatility. The item data provided offers a comprehensive overview of the lens's specifications, making it a valuable resource for those considering this component for their optical systems.
