Knight Optical’s resolution charts consist of multiple precision metallic patterns deposited on a transparent glass substrate and are equipped with a range of spatial frequencies for optical testing.
Resolution charts are used to test the resolving power of microscopes for medical and laboratory applications, and scanners and imaging cameras for defence and commercial applications. Knight Optical are able to provide USAF 1951 0-7, NBS 1963A and Cobb (BS1613) charts for resolution testing.
