AC127-030-A-ML 12.7 mm Dia. N-BK7/SF2 Mounted Achromatic Doublet; EFL=30mm 400-700nm
The AC127-030-A-ML is a mounted achromatic doublet lens from Thorlabs, designed for use in the 400-700nm spectral range. This lens is a part of Thorlabs' extensive catalog of optical elements, sourced from various vendors worldwide, and is available for purchase on their official website.
The lens features a 12.7 mm diameter and a total thickness of 3.4 mm at the edge. The inner and outer radii are 0, and the first and second radii of curvature are 17.9 mm and -13.5 mm, respectively. The third radius of curvature is -44.2 mm. The center thicknesses of the lens are 3.5 mm and 1.5 mm for the first and second surfaces, respectively.
The lens is made from two types of materials: n-BK7 Schott and SF2 Schott. The first surface is coated with tho ac400-700-a, and the second surface also features the same coating. This coating enhances the lens' performance in the 400-700nm spectral range, making it suitable for various applications.
The lens is a multiplet, meaning it is composed of multiple elements to achieve superior optical performance. The multiplet design allows for improved chromatic correction and reduced spherical aberration, making this lens an excellent choice for a wide range of optical systems.
