AC127-025-C 12.7 mm Dia. N-LAK22/N-SF6 Unmounted Achromatic Doublet; EFL=25mm 1050-1700nm
The AC127-025-C is an unmounted achromatic doublet lens, part of Thorlabs' extensive catalog of optical elements. This lens is designed for use in the 1050-1700nm wavelength range, making it suitable for a variety of applications in the near-infrared spectrum.
The lens features a base shape of a circular multiplet, with a diameter of 12.7mm. The geometry of the lens is defined by its inner and outer radii, which are both zero, and its three radii of curvature (r1, r2, and r3) of 12mm, -12.9mm, and 151.7mm respectively. The lens has a thickness of 4.6mm at the edge and 4.7mm and 1.5mm at the center.
The lens is made from two types of Schott glass, N-LAK22 and N-SF6, which are specified in the Material ID field. These materials are chosen for their optical properties, which contribute to the lens's overall performance.
The lens is coated with Thorlabs' AC1050-1700-C coating on both the front and back surfaces. This coating is designed to enhance the lens's performance in the 1050-1700nm wavelength range.
