AC508-150-A-ML 50.8 mm Dia. N-BK7/SF5 Mounted Achromatic Doublet; EFL=150mm 400-700nm

The AC508-150-A-ML is a mounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens, with a diameter of 50.8 mm, is designed for use in the spectral range of 400-700nm, making it suitable for a wide range of applications in the visible spectrum.

The lens is a multiplet, meaning it is composed of multiple elements. The primary materials used in its construction are N-BK7 and SF5, both high-quality glasses produced by Schott. The use of these materials ensures high transmission and low dispersion, contributing to the lens's excellent optical performance.

The lens's geometry is carefully designed to optimize its optical properties. It has an outer radius of 0mm, an inner radius of 0mm, and a diameter of 50.8mm. The edge thickness is 9.7mm, while the center thicknesses are 12mm and 3mm for the first and second centers, respectively. The lens's curvature is defined by radii of 83.2mm, -72.1mm, and -247.7mm for the first, second, and third surfaces, respectively.

The lens is coated with Thorlabs' AC400-700-A coating on both the front and back surfaces. This anti-reflection coating is designed to minimize reflection losses in the 400-700nm range, further enhancing the lens's performance.

The lens is mounted, making it ready for immediate use in optical systems. The vendor for this item is Thorlabs, a trusted name in the optical components industry. The item's catalog number is AC508-150-A-ML, and it is currently in stock, according to the vendor's website.
