AC254-500-B-ML 25.4 mm Dia. N-SF10/N-SF6HT Mounted Achromatic Doublet; EFL=500mm 650-1050nm

The AC254-500-B-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the spectral range of 650-1050nm, making it ideal for a variety of applications within this range.

The lens features a diameter of 25.4mm, providing a substantial surface area for light transmission. The edge thickness of the lens is 5.6mm, contributing to its robustness and durability. The lens's geometry is complex, with three radii (r1, r2, r3) and two central thicknesses, which are 4mm and 2mm respectively. This complex geometry is designed to optimize the lens's performance in its intended application range.

The lens is composed of two materials, n-sf10 schott and n-sf6ht schott. These materials are chosen for their specific optical properties, which contribute to the lens's overall performance. The lens is coated with tho ac650-1050-b on both the front and back surfaces, further enhancing its performance within the 650-1050nm spectral range.

The lens is a multiplet, meaning it is composed of multiple elements. This design allows for the correction of chromatic aberrations, providing a clear, focused image. The lens is mounted, making it easy to integrate into existing systems or to use as a standalone component.
