AC300-080-B 30 mm Dia. N-LAK22/N-SF6HT Unmounted Achromatic Doublet; EFL=80mm 650-1050nm

The AC300-080-B is a high-quality, unmounted achromatic doublet lens from Thorlabs, designed for use in the 650-1050nm spectral range. This lens, with a diameter of 30 mm, is a multiplet type, featuring a complex geometry that ensures superior optical performance.

The lens's geometry includes a 5.8 mm thickness at the edge, a 6.5 mm thickness at the center of the first surface, and a 2 mm thickness at the center of the second surface. The first and second surfaces have radii of curvature of 52.5 mm and -42.7 mm, respectively, while the third surface has a radius of -216.3 mm. The lens is made from two types of Schott glass, N-LAK22 and N-SF6HT, which are renowned for their excellent optical properties.

The lens is coated with Thorlabs' proprietary AC650-1050-B coating on both the front and back surfaces, designed to enhance its performance in the 650-1050nm spectral range. This coating ensures high transmission and low reflectance, making the lens ideal for use in a wide range of applications, including imaging, spectroscopy, and beam shaping.

The lens is unmounted, providing users with the flexibility to integrate it into their optical systems in the most suitable way. It is currently in stock and available for immediate shipping, as indicated by its valid weblink status.
