AC127-075-C 12.7 mm Dia. N-BAF10/N-SF6 Unmounted Achromatic Doublet; EFL=75.1mm 1050-1700nm

The AC127-075-C is a high-quality, unmounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the 1050-1700nm wavelength range, making it an ideal choice for a variety of applications within the infrared spectrum.

The lens features a base shape of a circle, with a diameter of 12.7mm. It has a thickness of 3.9mm at the edge, and its geometry includes an inner radius of 0mm and an outer radius of 0mm. The lens's first radius of curvature (r1) is 23.2mm, while its second radius of curvature (r2) is -27.9mm, and its third radius of curvature (r3) is 66.7mm. The thickness at the center of the lens is 3mm for the first center thickness and 1.5mm for the second center thickness.

The lens is composed of two materials: N-BAF10 and N-SF6, both from Schott. These materials have been carefully selected for their optical properties, ensuring high-quality performance across the specified wavelength range.

The lens is coated with Thorlabs' proprietary AC1050-1700-C coating on both the front and back surfaces. This coating is designed to enhance the lens's performance within the 1050-1700nm wavelength range, providing improved transmission and reduced reflection.

The lens is classified as a multiplet, indicating that it is composed of multiple optical elements. This design allows for the correction of various optical aberrations, resulting in a lens with superior image quality.
