The microscope includes an objective that irradiates a sample with excitation light and converts fluorescence from the sample into a parallel light flux, a beam splitter that splits fluorescence and excitation light from each other, and a collective lens that is arranged in such a manner that it is freely set in and removed from an optical path between the beam splitter and the objective, that has a positive power, and that is set in the optical path for fluorescence observation and is removed from the optical path for bright-field observation."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Microscope switchable between bright-field observation and fluorescence observation having movable lens","description":"A microscope is a microscope that switches an observation method between the bright-field observation and the fluorescence observation.
