Abstract
An endoscope system includes: an endoscope with a unit to be inserted into a subject and captures an inside image of the subject by an imaging unit provided in the unit to generate an image signal; an optical apparatus including a measurement probe to be inserted into the subject through the unit; an endoscope unit that switches between observation light of a plurality of wavelengths and outputs the observation light to observe a target object from the unit; a probe unit that outputs measurement light to measure characteristics of the target object via the measurement probe; a light unit that receives return light via the measurement probe, the return light caused by reflection and/or scattering of the measurement light on the target object; and a switching unit that switches a wavelength band of the measurement light to a different wavelength band from the observation light outputted by the endoscope unit.
