PURPOSE:To observe an object easily by providing the titled device with an image guide fiber in which the end surface parts of respective fiber elements are arrayed correspondingly in the same status and an objective optical system to form the image of the object to be observed. CONSTITUTION:The image guide fiber 1 is obtained by bundling many thin photoconductive fiber elements 2 tightly, arraying the end surface parts of these fiber elements correspondingly in the same status at the end surfaces 3, 4 of the object and eyepiece sides respectively and fixing the end surface parts with an adhesive 5 respectively. The image of the object to be observed is formed on the end surface 3 of the objective side by an objective optical system 8. In this invention, the parts other than the core part are inconspicious at the observation of the end surface of the eyepiece side, so that the end surface can be easily observed and the fatigue of eyes can be extremely reduced. |
