AC127-019-B-ML 12.7 mm Dia. N-BAF10/N-SF6HT Mounted Achromatic Doublet; EFL=19mm 650-1050nm

The AC127-019-B-ML is a high-quality mounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is specifically designed for use within the spectral range of 650-1050nm, making it suitable for a wide range of applications within this wavelength range.

The lens features a base shape of a circle, with a diameter of 12.7mm, providing a wide field of view. The lens is constructed from two types of Schott glass, N-BAF10 and N-SF6HT, each with its unique optical properties, contributing to the lens's overall performance. The lens's geometry includes an inner radius of 0mm, an outer radius of 0mm, and a thickness at the edge of 3.9mm. The curvature radii are r1=12.2mm, r2=-10.6mm, and r3=-77.4mm, providing the lens with its unique optical characteristics.

The lens's centers have different thicknesses, with the first center being 4.5mm and the second being 1.5mm. This asymmetry in thickness can contribute to the lens's ability to correct chromatic aberrations. The lens is coated with Thorlabs' proprietary anti-reflection coating, AC650-1050-B, on both the front and back surfaces, further enhancing its performance by reducing surface reflections and increasing transmission.

The lens is mounted, making it easy to integrate into optical systems. The mounting details are not provided in the item data, so it is recommended to check the vendor's website or contact them directly for more information.
