AC080-020-B-ML 8 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=20mm 650-1050nm
The AC080-020-B-ML is a mounted achromatic doublet lens, sourced from Thorlabs, designed for use within the 650-1050nm wavelength range. This lens is part of the Multiplets subtype, featuring a base shape of a circle and a geometry that includes an 8mm diameter, 2.8mm thickness at the edge, and varying radii and thicknesses at the center points.
The lens is composed of two materials, N-LAK22 and N-SF6HT, both from Schott. These materials have been carefully selected to optimize the lens's performance within its designated wavelength range. The lens is further enhanced with anti-reflection coatings on both the front and back surfaces, specifically the THo AC650-1050-B coating, which is designed to reduce surface reflections and increase transmission within the specified wavelength range.
This lens is a multiplet, meaning it is composed of multiple elements to achieve superior optical performance. The precise arrangement and alignment of these elements are crucial to the lens's ability to correct chromatic aberrations, a common issue in optical systems where different wavelengths of light are focused at different points. By minimizing these aberrations, the AC080-020-B-ML provides clear, high-quality images across its entire wavelength range.
