AC254-200-B-ML 25.4 mm Dia. N-LAK22/N-SF10 Mounted Achromatic Doublet; EFL=200mm 650-1050nm

The AC254-200-B-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is part of the multiplets category, featuring a base shape of a circle and a diameter of 25.4 mm. The lens is designed for use within the spectral range of 650-1050nm, making it suitable for a wide range of applications in the near-infrared region.

The lens is constructed from two types of materials, both from Schott: N-LAK22 and N-SF10. These materials are known for their excellent optical properties, contributing to the high performance of the lens. The lens features a thick edge of 7.3 mm and an inner radius of 0 mm, with outer radius also at 0 mm. The curvature radii are r1=106.4 mm, r2=-96.6 mm, and r3=2000 mm. The lens has two centers with equal thicknesses of 4 mm each.

The lens is coated with a broadband anti-reflection coating, specifically the Thorlabs AC650-1050-B coating, on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission within the specified spectral range.

The lens is mounted, making it ready for immediate use in optical systems. The detailed catalog number, AC254-200-B-ML, allows for easy identification and ordering. According to the vendor's information, the lens is currently in stock, ensuring quick delivery upon order.
