Abstract
A medical optical system includes an observation optical system for guiding light emitted from a light source to a predetermined part to be illuminated, and causing light reflected from the predetermined part to be incident on the observation optical system. The medical optical system further includes a light separator, a guide optical system, and a display unit. The light separator is disposed at an intermediate part of the observation optical system, for separating the reflected light into reflected light of a visible observation wavelength area to be passed therethrough and reflected light or fluorescent light of the other wavelength area to be extracted therefrom. The guide optical system guides the light separated and extracted by the light separator to an image pick-up device so that an image of the separated light is formed on the image pick-up device. And the display unit displays the separated light image picked up by the image pick-up device.
