Each tiltable lens is movable from a first variable angle to a second variable angle, with respect to its sensor, so that the respective lens plane and its sensor plane substantially intersect at the object plane in accordance with the Scheimpflug principle and the respective image is in focus across the whole field of view and of uniform light intensity."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method and apparatus for determining coplanarity in integrated circuit packages","description":"A method and apparatus for determining coplanarity of three-dimensional features on a substrate comprises a support for an object to be inspected in an object plane, a light source for illuminating th","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9594028","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
