First modulation light (L3) passing through the polarization element (20) again and then reflected by the light splitting surface (11) and second modulation light (L5) passing through the polarization element (40) again and then transmitted through the light splitting surface (11) are combined with each other."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical module and light exposure device","description":"An optical module (1A) includes a polarization beam splitter (10A), polarization elements (20 and 40) having nonreciprocal optical activity and respectively arranged on an optical path of a first pola","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9784980","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.
