ACN254-100-B 25.4 mm Dia. N-BAF10/N-SF6HT Unmounted Achromatic Doublet; EFL=-100.1mm 650-1050nm

The ACN254-100-B is a high-quality achromatic doublet lens from Thorlabs, designed for use in the 650-1050nm spectral range. This lens is part of Thorlabs' extensive catalog of optical elements, which includes a wide variety of lenses, mirrors, and other components sourced from vendors worldwide.

The lens features a 25.4mm diameter and a thickness of 6.9mm at the edge. It is designed in a circular shape, with a base shape that allows for versatile application. The lens's geometry includes an inner radius of 0 and an outer radius of 0, with curvature radii of r1=-48.8, r2=59, and r3=-580.8. The center thicknesses are 2mm and 3.4mm for the first and second centers, respectively.

The lens is made from two types of Schott glass: N-BAF10 and N-SF6HT. These materials are chosen for their excellent optical properties, which contribute to the lens's high performance. The lens is coated with Thorlabs' AC650-1050-B coating on both the front and back surfaces, further enhancing its performance in the specified spectral range.

The ACN254-100-B is a multiplet lens, meaning it is composed of multiple elements. This design allows for superior optical performance, making it suitable for a wide range of applications. The lens is unmounted, providing users with the flexibility to integrate it into their own systems and setups.
