Patent ID: 8773521

Claim:
An endoscope apparatus comprising: an inserted portion to be inserted inside a body cavity; a first dichroic mirror, disposed in a distal end portion of the inserted portion, the first dichroic minor being configured to deflect light of a first wavelength band in a longitudinal axial direction of the inserted portion, and transmit light of a second wavelength band in the longitudinal axial direction, thereby multiplexing the light of the second wavelength band with the light of the first wavelength band, the light of the first wavelength band being incident on the first dichroic mirror in a radial direction of the inserted portion and the light of the second wavelength being incident on the first dichroic minor in the longitudinal axial direction; a second dichroic mirror that splits the light multiplexed by the first dichroic mirror into each of the first wavelength band and the second wavelength band; and two image-acquisition units that respectively acquire the light in the first and second wavelength bands split by the second dichroic mirror.
