AC254-075-C-ML 25.4 mm Dia. N-BAF10/N-SF6HT Mounted Achromatic Doublet; EFL=75mm 1050-1700nm

The AC254-075-C-ML is a multiplet lens, specifically an achromatic doublet, sourced from Thorlabs. This lens boasts a 25.4 mm diameter and an effective focal length (EFL) of 75mm, making it suitable for a wide range of optical applications. The lens is designed for use within the spectral range of 1050-1700nm, as indicated by its coating, THo AC1050-1700-C.

The lens is composed of two materials, N-BAF10 and N-SF6HT, both from Schott. These materials are chosen for their specific refractive indices and dispersion properties, which contribute to the lens's achromatic design. This design ensures that the lens focuses different wavelengths of light onto the same point, reducing chromatic aberration.

The lens geometry is intricately designed with various radii and thicknesses to optimize its performance. The edge thickness is 7.1mm, while the center thicknesses are 7.6mm and 1.8mm. The inner and outer radii are 0mm, and the lens has three additional radii (r1, r2, r3) that contribute to its unique optical properties.

The lens is mounted, making it ready for immediate use in optical systems. The vendor, Thorlabs, indicates that this item is in stock, and the weblink provided leads directly to the product page for further information or purchase.
