AC508-1000-B 50.8 mm Dia. N-BAF10/N-SF10 Unmounted Achromatic Doublet; EFL=1000mm 650-1050nm

The AC508-1000-B is a high-quality achromatic doublet lens, featuring a 50.8 mm diameter and a focal length of 1000mm. This lens is designed for use in the 650-1050nm spectral range, making it suitable for a wide range of applications in the near-infrared region.

The lens is composed of two elements, made from N-BAF10 and N-SF10 Schott glass, which are renowned for their excellent optical properties. These materials help to minimize chromatic aberration, ensuring sharp and clear images. The lens features a multiplet geometry, with radii of curvature of r1=494.3mm, r2=-398.1mm, and r3=3440mm.

The lens has a thickness of 6.4mm at the edge and 4.2mm and 2.8mm at the center. Despite its robust construction, the lens is lightweight and easy to handle. It is unmounted, providing users with the flexibility to integrate it into their own systems.

The lens is coated with the THo AC650-1050-B coating on both the front and back surfaces, which enhances its transmission in the 650-1050nm range. This coating also helps to protect the lens from environmental factors, ensuring its longevity and durability.

The lens is available from Thorlabs, a leading vendor in the field of optical components. According to the vendor's website, the lens is currently in stock, indicating its availability for immediate purchase and delivery.
