AC127-050-B 12.7 mm Dia. N-BAF10/N-SF6HT Unmounted Achromatic Doublet; EFL=50mm 650-1050nm

The AC127-050-B is a high-quality unmounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the 650-1050nm wavelength range, making it suitable for a wide array of optical applications.

The lens features a 12.7 mm diameter and a total thickness of 4.2 mm at the edge. The inner and outer radii are 0, and the first and second radii of curvature are 24.2 mm and -26.8 mm, respectively. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF6HT, which are renowned for their optical clarity and durability.

The AC127-050-B is coated with Thorlabs' proprietary anti-reflection coating, AC650-1050-B, on both the front and back surfaces. This coating is designed to reduce surface reflections and increase transmission within the specified wavelength range.

The lens is a multiplet, meaning it is composed of multiple elements to achieve superior optical performance. The center thicknesses of the first and second elements are 3.5 mm and 1.5 mm, respectively. The lens is circular in shape, with no mount, allowing for easy integration into various optical systems.
