According to the present invention, a sample is illuminated through an objective lens used for capturing an image, and an imaging optics are provided with an aperture filter so that an image is captured while light of bright-field observation components is significantly attenuated."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical microscope device and testing apparatus comprising same","description":"The present invention allows observation or capturing of a high-contrast image of a sample for which sufficient contrast cannot be obtained in bright-field observation, such as a wafer having a patter","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9851548","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.
