AC080-030-B 8 mm Dia. N-LAK22/N-SF6 Unmounted Achromatic Doublet; EFL=30mm 650-1050nm

The AC080-030-B is an unmounted achromatic doublet lens, part of Thorlabs' extensive catalog of optical elements. This lens is designed for use within the 650-1050nm wavelength range, making it suitable for a variety of applications in the near-infrared spectrum.

The lens features a base shape of a circle, with a diameter of 8mm and a thickness at the edge of 3.5mm. The inner and outer radii are both zero, indicating a uniform curvature. The first radius of curvature (r1) is 18.5mm, while the second radius (r2) is -16.2mm, and the third radius (r3) is -106mm. The thickness at the center of the first surface is 2.5mm, and at the second surface is 1.5mm.

The lens is composed of two materials: N-LAK22 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' AC650-1050-B 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 optical elements. The specific arrangement and design of these elements contribute to the lens's achromatic properties, helping to minimize chromatic aberration and provide clear, focused images.
