AC254-040-B-ML 25.4 mm Dia. N-BAF10/N-SF6HT Mounted Achromatic Doublet; EFL=40mm 650-1050nm

The AC254-040-B-ML is a high-quality mounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is specifically designed for use within the spectral range of 650-1050nm, making it suitable for a wide range of applications within this wavelength range.

The lens features a base shape of a circle, with a diameter of 25.4mm, and is constructed from two types of Schott glass, N-BAF10 and N-SF6HT. This combination of materials and design ensures superior optical performance, minimizing chromatic aberration and delivering high-resolution images.

The lens geometry is intricately designed, with an edge thickness of 8.6mm, an inner radius of 0mm, and an outer radius of 0mm. The first and second radii of curvature are 26.12mm and -21.28mm respectively, while the third radius of curvature is -137.09mm. The lens has two centers of thickness, the first being 10mm and the second being 2.5mm.

The lens is coated with Thorlabs' proprietary anti-reflection coating, AC650-1050-B, on both the front and back surfaces. This coating is specifically designed to reduce surface reflections and increase transmission within the 650-1050nm spectral range.

The lens is mounted, making it easy to integrate into existing optical systems. The mounting details are not specified in the provided data, so it is recommended to refer to the vendor's specifications for more information.
