A concave mirror face is disposed so scanning light reflected by the reflecting face is incident on a subject's eye ocular fundus when the eye is at the concave mirror's focal point, and is arranged such that, when the eye is at the concave mirror's focal point, and when the light source emits fixation target light, that light and scanning light are simultaneously incident on the ocular fundus via different optical paths propagating via the concave mirror face and focal point, the target fixation light following a predetermined optical path for fixing the subject's eye gaze."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Ophthalmic device","description":"An ophthalmic device comprising a light source to emit fixation target light, and a reflecting face to reflect scanning light emitted by an emission section and scan the scanning light in a specific d","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11253146","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.
