AC254-060-B 25.4 mm Dia. N-LAK22/N-SF6HT Unmounted Achromatic Doublet; EFL=60mm 650-1050nm
The AC254-060-B is a high-quality achromatic doublet lens from Thorlabs, designed for use in the 650-1050nm spectral range. This lens is part of Thorlabs' extensive catalog of optical elements, which includes a wide variety of lenses, mirrors, and other components sourced from vendors worldwide.
The lens features a 25.4mm diameter and a focal length of 60mm, making it suitable for a wide range of optical applications. It is constructed from two types of Schott glass, N-LAK22 and N-SF6HT, which are known for their excellent optical properties. The lens is unmounted, allowing for easy integration into existing optical systems.
The AC254-060-B is coated with Thorlabs' AC650-1050-B coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the 650-1050nm spectral range.
The lens geometry includes a central thickness of 6mm, with additional thicknesses of 1.7mm at the edges. The lens also features a complex curvature, with radii of 39.48mm, -33mm, and -165.2mm, which helps to minimize chromatic aberration and ensure high-quality imaging.
