AOM - Cylinder Computer-Generated Holograms for Cylindrical Optics Testing

Cylinder computer-generated holograms (CGH) by AOM are sophisticated diffractive optical elements innovatively crafted to transform a collimated interferometer wavefront into a precisely focused cylindrical wavefront. These elements allow the accurate confocal null testing of both concave and convex cylindrical optics, with flexible testing configurations achievable by positioning optics within converging or diverging wavefronts. AOM provides a diverse array of cylinder CGHs, each uniquely engineered to accommodate various interferometer outputs, with sizes ranging from 2 to 6 inches. Their application extends over a breadth of cylindrical optics metrology tasks, particularly those necessitating compatibility with commercial interferometers. Standard models are available with mechanical cell mounts that seamlessly interface with AOM’s fine alignment stages. Whether seeking a stock solution or a custom-designed hologram for specific wavelengths beyond the standard 633 nm, AOM offers a range of purchasing and customization options through platforms such as the Edmund Optics catalog.
