The apparatus further comprises a photo-detector (206) for detecting light incident on the photo-detector (206); and an interference filter (204; 304) arranged on the photo-detector (206), wherein the interference filter (204; 304) is configured to selectively collect and transmit light towards the photo-detector (206) based on an angle of incidence of the light towards the interference filter (204; 304), wherein the interference filter (204; 304) is configured to selectively transmit supercritical angle light from the sample towards the photo-detector (206) and suppress undercritical angle light from the sample."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Apparatus and method for detecting photoluminescent light emitted from a sample","description":"The present invention provides an apparatus for detecting photoluminescent light emitted from a sample, said apparatus (200; 300) comprising at least one light source (210; 310, 318), which is configu","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-12000785","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.
