The system allows causing an electromagnetic beam to access an otherwise difficult to access sample in, for instance, a vacuum deposition chamber, and enables achieving very closely spaced incident and spherical mirror reflected points of beam reflection from a sample surface in use."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ellipsometers and polarimeters comprising polarization state compensating beam directing sample wobble compensating system, and method of use","description":"An improved system and method for investigation of a wobbling surface of a sample with an electromagnetic beam, involving application of a beam directing dual reflection surface “prism” system, which,","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8467057","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.
