ILLUMINATION DEVICE FOR TUMOR DETECTION AND ILLUMINATION DEVICE FOR EXAMINATIONS

摘要

The present invention is an illumination device for tumor detection, which improves the visibility of a tumor in which a fluorescent substance is accumulated, and emits excitation light for the fluorescent substance accumulated in the tumor, and the illumination device for tumor detection is provided with: a light emitting diode that emits light of which a wavelength range substantially coincides with an excitation wavelength range for the fluorescent substance; and a blocking part that is provided on a light emission side of the light emitting diode, and blocks the same wavelength as at least a part of the excitation wavelength range for the fluorescent substance.
