AC254-125-A-ML 25.4 mm Dia. N-BK7/N-SF5 Mounted Achromatic Doublet; EFL=125mm 400-700nm

The AC254-125-A-ML is a high-quality mounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is specifically designed for use in the 400-700nm spectral range, making it suitable for a wide range of applications in the visible light spectrum.

The lens features a 25.4mm diameter and a focal length of 125mm, as indicated by its EFL (Effective Focal Length) value. The doublet design consists of two elements, made from N-BK7 and N-SF5 materials, respectively. These materials, both from Schott, are known for their excellent optical properties, contributing to the lens' high performance.

The lens is coated with Thorlabs' AC400-700-A coating on both the front and back surfaces. This anti-reflection coating is designed to reduce surface reflections and increase transmission in the 400-700nm range, further enhancing the lens' performance.

The lens geometry includes a thickness of 5mm at the edge, with the center thicknesses of the two elements being 4mm and 2.8mm, respectively. The lens's base shape is circular, and it features a multiplet shape, which is a composite lens made up of several simple lenses.
