ACN127-030-A 12.7 mm Dia. N-BAK4/SF5 Unmounted Achromatic Doublet; EFL=-30mm 400-700nm
The ACN127-030-A is a high-quality achromatic doublet lens from Thorlabs, designed for use in the 400-700nm spectral range. This lens is part of Thorlabs' extensive catalog of optical elements, which 3DOptix integrates into its advanced optical simulation software.
The lens features a 12.7 mm diameter and a center thickness of 1.5mm for the first element and 2.3mm for the second. The lens is constructed from two elements, the first being N-BAK4 from Schott and the second being SF5 from Schott. This combination ensures high-quality imaging and minimal chromatic aberration.
The lens is coated with THo AC400-700-A, a broadband anti-reflection coating designed for use in the 400-700nm range. This coating reduces surface reflections and increases transmission, enhancing the overall performance of the lens.
The lens is unmounted, providing users with the flexibility to integrate it into their own optical systems. The lens geometry includes an inner radius of 0mm, an outer radius of 0mm, r1 of -16.2mm, r2 of 16.5mm, and r3 of 154.2mm.
According to Thorlabs' website, the lens is currently in stock, making it readily available for immediate use. The lens's catalog number is ACN127-030-A, and it can be found on Thorlabs' website for further information.
