AC254-030-B-ML 25.4 mm Dia. N-BAF10/N-SF6HT Mounted Achromatic Doublet; EFL=30mm 650-1050nm

The AC254-030-B-ML is a mounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the spectral range of 650-1050nm, making it suitable for a wide range of optical applications within this range.

The lens features a base shape of a circle, with a diameter of 25.4mm. The edge thickness of the lens is 8.2mm, while the inner and outer radii are 0mm. The lens's first radius of curvature (r1) is 21.09mm, the second radius (r2) is -16.18mm, and the third radius (r3) is -79.08mm. The center thickness of the lens is 12mm for the first center and 1.5mm for the second center.

The lens is composed of two materials: N-BAF10 and N-SF6HT, both from Schott. These materials have been carefully selected for their optical properties, ensuring the lens performs optimally within its designated spectral range.

The lens is coated with a front and back coating of tho ac650-1050-b. This coating enhances the lens's performance within the 650-1050nm spectral range, providing improved transmission and reduced reflection.

The lens is a multiplet, meaning it is composed of multiple elements. This design allows for the correction of optical aberrations, providing a higher quality image than a single element lens.

The lens is currently in stock and available for purchase through the Thorlabs website. The catalog number for this lens is AC254-030-B-ML.
