AC254-200-A-ML 25.4 mm Dia. N-SSK5/LAFN7 Mounted Achromatic Doublet; EFL=200mm 400-700nm

The AC254-200-A-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is part of Thorlabs' extensive catalog of optical elements, which 3DOptix integrates into its advanced optical simulation software. The lens is specifically designed for use within the 400-700nm wavelength range, making it suitable for a wide range of optical applications.

The lens features a base shape of a circle, with a diameter of 25.4mm. The edge thickness of the lens is 5.7mm, while the inner and outer radii are 0mm. The lens's first and second radii of curvature are 77.4mm and -87.6mm, respectively, and the third radius of curvature is 291.1mm. The lens has two centers of thickness, the first being 4mm and the second being 2.5mm.

The lens is made from two types of materials, namely n-ssk5 schott and lafn7 schott. These materials are specifically chosen for their optical properties, which contribute to the lens's overall performance. 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 optical elements. This design allows for the correction of various optical aberrations, resulting in a lens with high optical quality. The lens is mounted, making it easy to integrate into optical systems.

According to Thorlabs' website, the lens is currently in stock, indicating its availability for immediate use. The lens's catalog number is AC254-200-A-ML, and it can be found on Thorlabs' website for further information.
