AC254-075-C 25.4 mm Dia. N-BAF10/N-SF6 Unmounted Achromatic Doublet; EFL=75.1mm 1050-1700nm

The AC254-075-C is a 25.4 mm diameter achromatic doublet lens, designed and manufactured by Thorlabs. This unmounted lens is specifically engineered for use within the 1050-1700nm wavelength range, making it suitable for a variety of applications within the near-infrared spectrum.

The lens features a geometry that includes an edge thickness of 7.1mm, and a center thickness of 7.6mm for the first surface and 1.8mm for the second surface. The lens's base shape is circular, with a diameter of 25.4mm. The lens's design includes three radii: r1 at 26.4mm, r2 at -29.4mm, and r3 at 84.9mm. The inner and outer radii are both zero.

The lens is composed of two materials: N-BAF10 and N-SF6, both from Schott. 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, further enhancing its performance within the specified wavelength range.

This lens is classified as a multiplet, indicating that it is composed of multiple elements. The multiplet design helps to correct chromatic aberrations, making the lens suitable for a wide range of applications.
