AC127-019-C 12.7 mm Dia. N-LAK22/N-SF6 Unmounted Achromatic Doublet; EFL=19mm 1050-1700nm
The AC127-019-C is a high-quality unmounted achromatic doublet lens, designed and manufactured by Thorlabs. This lens is specifically engineered for use within the 1050-1700nm wavelength range, making it an ideal choice for a wide range of optical applications.
The lens features a 12.7 mm diameter and a thickness of 4.4 mm at the edge, ensuring durability and robustness. The base shape is circular, with an inner radius of 0 and an outer radius of 0. The r1, r2, and r3 parameters are 12.4 mm, -10 mm, and -48.8 mm respectively, providing excellent optical performance.
The lens is composed of two materials, N-LAK22 and N-SF6, both from Schott. These materials have been carefully selected for their optical properties, ensuring high-quality performance across the specified wavelength range.
The lens is coated with Thorlabs' proprietary AC1050-1700-C coating on both the front and back surfaces. This coating is designed to enhance the lens' performance within the 1050-1700nm wavelength range, providing improved transmission and reduced reflection.
The lens is a multiplet, meaning it is composed of multiple optical elements. This design allows for the correction of chromatic aberrations, providing sharp, clear images even at the edges of the field of view.
