AC060-010-B 6 mm Dia. N-LAK22/N-SF6HT Unmounted Achromatic Doublet; EFL=10mm 650-1050nm

The AC060-010-B is an unmounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is designed for use within the spectral range of 650-1050nm, making it suitable for a wide range of applications within the near-infrared region.

The lens features a base shape of a circle, with a diameter of 6mm. The edge thickness of the lens is 2.3mm, while the center thicknesses are 2.5mm and 1.5mm respectively. The lens's geometry is further defined by its inner and outer radii, both of which are 0mm, and its three radii of curvature (r1, r2, r3) which are 7.1mm, -5.3mm, and -19.5mm respectively.

The lens is composed of two materials, N-LAK22 and N-SF6HT, both from Schott. These materials are chosen for their excellent optical properties within the near-infrared region. The lens is coated with a broadband anti-reflection coating, specifically the THo AR650-1050-B coating, on both the front and back surfaces to minimize losses due to reflection.

The lens is classified as a multiplet, indicating that it is composed of multiple elements. This design allows for the correction of chromatic aberrations, ensuring high-quality imaging across the entire spectral range. The lens is unmounted, providing users with the flexibility to integrate it into their own optical systems.
