AC050-010-B-ML 5 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=10mm 650-1050nm

The AC050-010-B-ML is a mounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens, with a diameter of 5 mm, is designed for use within the spectral range of 650-1050nm, making it suitable for a wide range of applications in the near-infrared region.

The lens is composed of two distinct materials, N-LAK22 and N-SF6HT, both from Schott. These materials are chosen for their specific refractive indices and dispersion properties, which contribute to the lens's achromatic design. This design ensures that the lens minimizes chromatic aberration, a common issue in lens systems where different wavelengths of light are focused at different points.

The lens geometry is intricately designed with various radii and thicknesses to optimize its performance. The edge thickness is 3.2 mm, while the center thicknesses are 2.2 mm and 1.6 mm for the first and second centers, respectively. The lens also features an effective focal length (EFL) of 10mm, a critical parameter in lens selection.

The lens is coated with Thorlabs' proprietary anti-reflection coating, THo AC650-1050-B, on both the front and back surfaces. This coating is specifically designed to reduce surface reflections within the lens's operational spectrum, further enhancing its performance and ensuring optimal light transmission.
