AC080-020-A 8 mm Dia. N-BK7/SF2 Unmounted Achromatic Doublet; EFL=20mm 400-700nm

The AC080-020-A is an unmounted achromatic doublet lens, a high-quality optical component designed and manufactured by Thorlabs. This lens is specifically designed for use in the 400-700nm wavelength range, making it suitable for a wide range of applications in the visible spectrum.

The lens features a diameter of 8mm and a total thickness of 3mm at the edge. It is composed of two distinct materials: N-BK7 from Schott and SF2 from Schott. These materials are carefully selected for their optical properties, contributing to the lens's overall performance.

The lens's geometry is characterized by its base shape, which is circular, and its radii of curvature. The first radius of curvature (r1) is 11.1mm, the second radius (r2) is -9.2mm, and the third radius (r3) is -34.8mm. The lens also has varying thickness at its center, with the first center thickness (thickness center 1) being 2.5mm and the second center thickness (thickness center 2) being 1.5mm.

The lens is coated with THo AC400-700-A on both the front and back surfaces, enhancing its performance in the specified wavelength range. The lens is classified as a multiplet due to its complex structure, which is designed to correct chromatic aberrations and improve image quality.
