AC254-250-A-ML 25.4 mm Dia. N-BK7/SF2 Mounted Achromatic Doublet; EFL=250mm 400-700nm

The AC254-250-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 within the 400-700nm wavelength range, making it suitable for a wide array of optical applications.

The lens features a base shape of a circle, with a diameter of 25.4mm. It has a thickness of 5.2mm at the edge, and its geometry includes an inner radius of 0mm and an outer radius of 0mm. The lens's first radius of curvature (r1) is 137.1mm, the second radius of curvature (r2) is -111.5mm, and the third radius of curvature (r3) is -459.2mm. The thickness at the center of the lens is 4mm for the first center and 2mm for the second center.

The lens is composed of two types of materials: n-BK7 from Schott and SF2 from Schott. This combination of materials helps to minimize chromatic aberration, a common issue in optical systems. The lens is coated with THo AC400-700-A on both the front and back surfaces, further enhancing its performance within the specified wavelength range.

The lens is a multiplet, meaning it is composed of multiple elements. This design allows for more precise control over the optical properties of the lens, making it ideal for applications that require high-resolution imaging or precise light control.
