AC064-015-A 6.35 mm Dia. N-BK7/SF2 Unmounted Achromatic Doublet; EFL=15mm 400-700nm

The AC064-015-A is a high-quality unmounted achromatic doublet lens, sourced from the renowned optical component manufacturer, Thorlabs. This lens is specifically designed for use within the spectral range of 400-700nm, making it suitable for a wide range of applications within the visible light spectrum.

The lens features a base shape of a circle, with a diameter of 6.35mm. The edge thickness of the lens is 3.2mm, ensuring robustness and durability. The lens's geometry includes an inner radius of 0mm and an outer radius of 0mm, with curvature radii of r1=8.8mm, r2=-6.6mm, and r3=-21.7mm. This complex curvature profile allows for superior optical performance.

The lens is composed of two types of glass, N-BK7 and SF2, both from Schott. These materials were chosen for their excellent optical properties, including high transparency and low dispersion. The lens is coated with THo AC400-700-A on both the front and back surfaces, further enhancing its performance within the specified spectral range.

The lens's shape is a multiplet, which is a combination of multiple individual lenses. This design provides enhanced optical performance, reducing chromatic and spherical aberrations. The lens has two central thicknesses: the first is 2.5mm, and the second is 1.5mm.
