Patent ID: 11395583

Abstract:
An endoscope light emitting device (1) is a light emitting device for use in a fluorescence imaging method. The endoscope light emitting device includes: a solid-state light emitting element (2); and a wavelength converter (3) including a first phosphor (4) that emits first wavelength-converted light (7), wherein the first wavelength-converted light has a light component across at least a whole of a wavelength range of 700 nm or more and 800 nm or less. An endoscope (11) includes the endoscope light emitting device. A fluorescence imaging method is a method using the endoscope light emitting device or the endoscope, and includes the steps of: administering a fluorescent drug to a subject; and applying the first wavelength-converted light (7) to the subject with whom the fluorescent drug has made contact.
