AC080-020-B 8 mm Dia. N-LAK22/N-SF6HT Unmounted Achromatic Doublet; EFL=20mm 650-1050nm

The AC080-020-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 spectral range, making it suitable for a wide range of applications in the near-infrared region.

The lens features a base shape of a circle, with a diameter of 8mm and a thickness at the edge of 2.8mm. The inner and outer radii are 0mm, indicating a flat profile. The lens's geometry is further defined by its three radii (r1, r2, and r3) and two center thicknesses. The first radius (r1) is 13.5mm, the second radius (r2) is -10.6mm, and the third radius (r3) is -47.8mm. The first center thickness is 2.3mm, and the second center thickness is 1.3mm.

The lens is composed of two materials: N-LAK22 and N-SF6HT, 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 spectral range.

Please note that the lens is unmounted, meaning it does not come with any housing or mounting mechanism. Users will need to provide their own mounting solution to integrate this lens into their optical system.
