AC508-075-C 50.8 mm Dia. N-BAF10/N-SF6 Unmounted Achromatic Doublet; EFL=75.4mm 1050-1700nm
The AC508-075-C is a high-quality achromatic doublet lens, designed and manufactured by Thorlabs. This lens, which has a diameter of 50.8 mm, is part of Thorlabs' extensive catalog of optical elements, and it is specifically designed for use in the 1050-1700nm spectral range.
The lens is a multiplet, meaning it is composed of multiple optical elements. The two materials used in this doublet lens are n-baf10 and n-sf6, both from Schott. These materials were chosen for their excellent optical properties in the specified spectral range. The lens is unmounted, providing users with the flexibility to integrate it into their own systems and setups.
The geometry of the lens is carefully designed to optimize its performance. The edge thickness of the lens is 13.1 mm, while the center thicknesses are 19 mm and 2.5 mm. The lens has a base shape of a circle, with radii of 49.9 mm, -39.1 mm, and -230.7 mm. The inner and outer radii are both 0 mm, indicating a symmetrical design.
Both the front and back surfaces of the lens are coated with Thorlabs' AC1050-1700-C coating. This coating is specifically designed to enhance the lens' performance in the 1050-1700nm spectral range, ensuring high transmission and low reflectance.
