A detector surface of the infrared detector, the window portion, the shutter, and the lens are arranged such that an inclination angle of a virtual straight line which connects each corner portion of the detector surface, the window portion and a maximum aperture of the shutter, and edge portion of an effective lens area of a lens closest to the shutter against to an optical axis is 25° to 35°, is adopted."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical arrangement of infrared camera","description":"Provided is an optical arrangement of the infrared camera comprising a lens unit in which a lens is supported by a frame body, an infrared detector module in which an infrared detector for detecting a","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8507859","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.
