Abstract

Abstract @ The present invention relates to the structure of an optical transmission channel (13) for use in a fiberscope, an optical fiber sensor or the like having an illuminating light transmission channel, an information light transmission channel and various kinds of auxiliary transmission channels. The optical transmission channel (13) is provided in its periphery with axially and extending grooves for receiving an image fiber (10) and a tube (12) for conducting fluid, the arrangement being such that the transmission channel has an almost circular section when the grooves are fitted with the image fiber and tube.
