AC254-080-B 25.4 mm Dia. N-BAF10/N-SF6HT Unmounted Achromatic Doublet; EFL=80.3mm 650-1050nm

The AC254-080-B is a high-quality achromatic doublet lens, unmounted and with a diameter of 25.4 mm, sourced from the renowned optical components manufacturer, Thorlabs. This lens is designed for use within the spectral range of 650-1050nm, making it suitable for a wide array of applications within this range.

The lens features a multilayer anti-reflection coating, specifically the tho ac650-1050-b coating, on both its front and back surfaces. This coating enhances the lens's performance by minimizing surface reflections, thereby increasing transmission and reducing the likelihood of unwanted optical artifacts such as ghosting and flaring.

The lens's geometry is characterized by a thickness of 6.4mm at the edge, with the inner and outer radii both being 0. The first and second radii of curvature (r1 and r2) are 38.7mm and -43.2mm, respectively, while the third radius of curvature (r3) is a substantial 374mm. The lens has two centers of thickness: the first center of thickness is 6.6mm, and the second is 2mm.

The lens is composed of two materials: N-BAF10 and N-SF6HT, both from the reputable glass manufacturer Schott. The combination of these materials and their respective properties contributes to the lens's excellent chromatic correction and overall optical performance.
