A fiberscope has a light source and a light guide for leading light emitted from the source onto an object disposed in liquid helium. A transmission system for transmitting the image of the object has an image guide. A body tube is fixed to one end of the image guide and faces the object. Objective lenses are disposed in the body tube to project the image of the object onto the one end face of the image guide. An eyepiece is fixed to the other end of the image guide, through which the image of the object is viewed. The interior of the body tube is kept under vacuum.
