Abstract

Abstract An apparatus is disclosed which includes a first and a second optical guides inserted in an elongated insertion portion thereof, and which can transmit an optical image, and an optical system with a function of imaging at the end surface of the optical guide. By transmitting an illuminating light from the other end surface to the portion to be observed through one of the optical guides, the portion to be observed is illuminated. While, the optical image transmitted through the other optical guide is introduced into an ocular system or an imaging system. By changing the functions performed by these optical guides, the stereoscopic observation and stereoscopic imaging can be realized.
