AC050-010-B 5 mm Dia. N-LAK22/N-SF6HT Unmounted Achromatic Doublet; EFL=10mm 650-1050nm
The AC050-010-B is a high-quality 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 5mm diameter and a thickness of 3.2mm at the edge. It is composed of two distinct materials, N-LAK22 and N-SF6HT, both from Schott, which are renowned for their optical quality. The lens geometry is complex, with radii of curvature of r1=6.6mm, r2=-5.3mm, and r3=-24.9mm, and center thicknesses of 2.2mm and 1.6mm. This complex geometry is designed to minimize chromatic aberration, a common issue in optical systems.
The lens is coated with Thorlabs' proprietary anti-reflection coating, AC650-1050-B, on both the front and back surfaces. This coating is specifically designed to reduce surface reflections within the 650-1050nm spectral range, thereby improving transmission and reducing unwanted optical artifacts.
