An image-side surface (S14) of the seventh lens (L7) is a concave surface at the optical axis. In addition, the optical system (100) satisfies 1<TTL/<2.5, wherein TTL is the distance between the object-side surface (S1) of the first lens (L1) and an imaging surface (S19) of the optical system (100) on the optical axis. The optical system (100) further comprises a diaphragm (STO), and L is the effective aperture diameter of the diaphragm (STO)."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Optical system, image capturing module and electronic device","description":"An optical system (100), sequentially comprising from an object side to an image side: a first lens (L1) having positive refractive power, an object-side surface (S1) of the first lens (L1) being a co","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11953756","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.
