The AC080-016-C-ML is an 8 mm diameter achromatic doublet lens, a multiplet type of lens, sourced from Thorlabs. This lens is designed for use within the extended infrared spectrum, specifically between 1050 and 1700 nanometers.
The lens features a geometry that includes a thickness of 3.8 mm at the edge, with the inner and outer radii being zero. The first and second radii of curvature are 7.5 mm and -7.8 mm, respectively, while the third radius of curvature is 68.5 mm. The lens has two centers with different thicknesses: the first center has a thickness of 3.5 mm, and the second center has a thickness of 1.3 mm.
The lens is composed of two materials: N-LAK22 from Schott and N-SF6HT from Schott. Both the front and back surfaces of the lens are coated with the THo AC1050-1700-C coating, which is specifically designed for use within the 1050-1700nm spectral range.
The lens is currently in stock and available for immediate purchase through the Thorlabs website. For more detailed information, including pricing and availability, please refer to the product's webpage on the Thorlabs website.
