The integrator optical system irradiates with the illumination light the area of irradiation that includes a reference area of measurement and is larger than the reference area of measurement by at least an allowable amount of change in the distance between the medium and the spectroscope or more, the reference area of measurement in which the distance between the medium and the spectroscope is equal to a reference distance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spectrometry device and image forming apparatus","description":"A printer includes a spectroscope including a light source, an integrator optical system that irradiates a predetermined area of irradiation of a medium with illumination light from the light source, ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9739662","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.
