Endoscope system

Abstract

An endoscope system including first and second light sources, first, second and third optical fibers, a first optical fiber coupler, a bidirectional coupler, and an optical fiber endoscope is provided. A wavelength of light emitted by the first light source is between 400 nm and 800 nm. The first optical fiber is connected to the first light source. A wavelength of light emitted by the second light source is between 900 nm and 1700 nm. The second optical fiber is connected to the second light source. The first optical fiber coupler is connected to the first and second optical fibers. The third optical fiber is connected to the first optical fiber coupler. The bidirectional coupler is connected to the third optical fiber. The optical fiber endoscope has a first end provided with a microlens array group, and a second end connected to the bidirectional coupler.
