AC127-025-B 12.7 mm Dia. N-LAK22/N-SF6HT Unmounted Achromatic Doublet; EFL=25mm 650-1050nm
The AC127-025-B is a high-quality, unmounted achromatic doublet lens from Thorlabs, designed for use in the 650-1050nm spectral range. This lens is a multiplet, meaning it is composed of multiple optical elements to achieve superior performance.
The lens features a 12.7 mm diameter and a total thickness of 5.4 mm at the edge. The inner and outer radii are 0, and the first, second, and third radii of curvature are 16.2 mm, -13.3 mm, and -68.5 mm, respectively. The lens is constructed from two types of Schott glass: N-LAK22 and N-SF6HT.
The AC127-025-B is coated with Thorlabs' proprietary anti-reflection coating, AC650-1050-B, on both the front and back surfaces. This coating is specifically designed for use in the 650-1050nm range, reducing surface reflections and improving transmission.
The lens has an effective focal length (EFL) of 25mm, making it suitable for a wide range of optical applications. The shape of the lens is circular, and it is unmounted, providing users with the flexibility to integrate it into their own systems and setups.
