AC127-075-A-ML 12.7 mm Dia. N-BK7/SF2 Mounted Achromatic Doublet; EFL=75mm 400-700nm
This is the AC127-075-A-ML, a multiplet lens by Thorlabs, designed with a 12.7 mm diameter and a focal length of 75mm, specifically optimized for the spectral range of 400-700nm. The lens is mounted and coated with Thorlabs' AC400-700-A coating on both the front and back surfaces, ensuring high transmission and durability within its specified wavelength range.
The lens is composed of two distinct materials: n-BK7 from Schott and SF2 from Schott. The first surface has a radius of curvature of 41.3mm, while the second surface has a radius of -34mm. The third surface, made of SF2, has a radius of curvature of -137.1mm. The lens's edge thickness is 3.4mm, with the center thicknesses at the first and second surfaces being 2.5mm and 1.5mm respectively.
The AC127-075-A-ML is a versatile lens, suitable for a wide range of optical applications. Its achromatic design ensures minimal chromatic aberration, making it ideal for imaging and beam shaping applications. The lens's specifications, coupled with Thorlabs' reputation for quality, make it a reliable choice for your optical needs.
