AC254-100-B-ML 25.4 mm Dia. N-LAK22/N-SF6HT Mounted Achromatic Doublet; EFL=100mm 650-1050nm

The AC254-100-B-ML is a mounted 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 variety of applications within this spectrum.

The lens features a 25.4mm diameter, providing a substantial surface area for light transmission. The lens is constructed from two types of Schott glass, N-LAK22 and N-SF6HT, each chosen for their specific optical properties. The use of these materials helps to minimize chromatic aberration, a common issue in optical systems.

The lens geometry is complex, with three radii of curvature (r1, r2, and r3) and varying thicknesses at the edge and center. This design allows for precise control over the lens's optical properties, enhancing its performance in achromatic applications.

The lens is coated with Thorlabs' proprietary AC650-1050-B coating on both the front and back surfaces. This coating is designed to enhance the lens's transmission within the specified wavelength range, further improving its performance.

The lens is mounted, providing a convenient and secure method of integration into optical systems. The mounting details are not specified in the provided data, so users should refer to the vendor's product page for more information.
