Abstract

PURPOSE:To adjust a visual field even when an object to be observed is narrow by making light incident to the eyepiece side of an optical transmission line, and then adjusting the visual field wherein observation is possible through the optical image transmission line on a basis of the spread of light emitted from an object side. CONSTITUTION:Light from a light source 2 for emitting the light for visual field adjustment is made incident to the eyepiece side 1a of an optical image transmission line 1 which uses a bundle of optical image fiber wires, a lens, a reflecting mirror, etc., in combination. As the light source 2, a high-brightness halogen lamp for a light guife, etc., is used. The incident light is emitted from the objective 1b of the optical image transmission line 1 via the opposite route to normal image transmission, but this emitted light while having a spread coincident to a visual field observed through the optical image transmission line 1 strikes an objective 3 to be observed. An observe adjusts distance L over an external look at the spread of the emitted light.
