Light intensities of a first pair of light beams extinguish each other in a first partial area of the focal area. Beam paths of the first pair of beams pass through the objectives in a first pair of partial areas of the pupils of the objectives. Light intensities of a second pair of light beams extinguish each other in a second partial area of the focal area. Beam paths of the second pair of light beams pass through the objectives in a second pair of partial areas which are offset with regard to the first pair of partial areas of the pupils; and the light of the second pair does not interfere with the light of the first pair of light beams."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"4Pi STED fluorescence light microscope with high three-dimensional spatial resolution","description":"An apparatus forming an area of minimum light intensity enclosed by high light intensity includes two objectives focusing light of opposite directions into a common focal area.
