Arizona Optical Metrology LLC offers consulting services and hardware for optical metrology challenges. The firm provides customers with design and analysis of optical null tests of aspheric surfaces called Computer Generated Holograms (CGHs). CGHs are often used in testing aspheric optics as the null lens or part of the null lens. Compared to other well known null lens type, it has the advantage of being able to create virtually any wavefront shape, not limited to axi-symmetric ones. The firm has researched developing very large CGHs for NASA that would be used in ground and space telescopes.
