AC080-020-C-ML 8 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=20mm 1050-1700nm

The AC080-020-C-ML is an achromatic doublet lens from Thorlabs, designed for use in the 1050-1700nm wavelength range. This lens is part of Thorlabs' extensive catalog of optical elements, sourced from vendors worldwide and integrated into 3DOptix's advanced optical simulation software.

The lens features a base shape of a circle, with an 8mm diameter. It has a thickness of 3.7mm at the edge and 3.3mm and 1.3mm at the center, providing a robust structure for various applications. The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, with curvature radii of 7.8mm, -8.6mm, and 31.9mm, contributing to its achromatic properties.

The lens is made from two types of Schott glass: N-LAK22 and N-SF6HT. These materials are chosen for their specific refractive indices and dispersion properties, which help to minimize chromatic aberration in the specified wavelength range. The lens is coated with Thorlabs' AC1050-1700-C coating on both the front and back surfaces, further enhancing its performance in the targeted wavelength range.

This lens is classified as a multiplet, indicating that it consists of multiple elements. The multiplet design allows for more complex optical properties, making it suitable for a wide range of applications. The lens is mounted, providing convenience and ease of use in optical systems.
