The circular polarization filter of the invention is capable of providing circularly polarized light with a high circular polarizance, or improving sensitivity in the sensor system using circularly polarized light."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Circular polarization filter and application therefor","description":"Provided are a circular polarization filter including a circularly-polarized light separating layer (preferably, a layer having a cholesteric liquid crystalline phase fixed therein or a laminate inclu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9759600","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.
