AC127-019-C-ML 12.7 mm Dia. N-LAK22/N-SF6 Mounted Achromatic Doublet; EFL=19mm 1050-1700nm
The AC127-019-C-ML is a multiplet lens, specifically an achromatic doublet, sourced from Thorlabs. This lens is designed for use in the 1050-1700nm wavelength range, making it suitable for a variety of applications within the near-infrared spectrum.
The lens features a 12.7 mm diameter and a thickness of 4.3 mm at the edge. The base shape is circular, and the lens is composed of two distinct materials: n-lak22 schott and n-sf6 schott. This combination of materials and design helps to minimize chromatic aberration, a common issue in optical systems.
The lens's geometry is characterized by an inner radius of 0 and an outer radius of 0. The first and second radii of curvature (r1 and r2) are 12.4 mm and -10 mm, respectively, while the third radius of curvature (r3) is -48.8 mm. The lens has two centers of thickness: the first is 5 mm, and the second is 1.5 mm.
Both the front and back surfaces of the lens are coated with tho ac1050-1700-c, a coating specifically designed for use in the 1050-1700nm wavelength range. This coating helps to enhance the lens's performance by reducing reflection and increasing transmission.
