Abstract
The distal end of an inserted portion, having a simple structure, is reduced in diameter, loss of light incident from a body cavity is reduced, and light from two different directions is observed simultaneously and in a separated fashion. Provided is an endoscope apparatus () including an inserted portion () to be inserted inside a body cavity; a first dichroic mirror (), disposed in a distal end portion of the inserted portion (), that transmits light (L) in a first wavelength band, which is incident from a longitudinal axial direction and that deflects light (L) in a second wavelength band, which is incident from a radial direction, in the longitudinal axial direction, thereby multiplexing it with the light (L) in the first wavelength band; a second dichroic mirror () that splits the light (L, L) multiplexed by the first dichroic mirror () into each wavelength band; and two image-acquisition units () that respectively acquire the light (L, L) in the first and second wavelength bands split by the second dichroic mirror ().
