Abstract

PURPOSE: To change over from exciting light to visible light and vice versa in a simple construction and also provide possibility of changing over between the fluorescent light and visible light by furnishing a rotary filter with a penetration part to admit penetration of visible range light, another penetration part to admit penetration of an exciting light, and a third to admit fluorescent light.
CONSTITUTION: The light flux of an object to be photographed 20, which is irradiated with the illumination light of a lamp 12, is focused by an objective lens 7 on the incident end-face of an image guide 8, conducted in this image guide 8, wave-divided by a rotary filter 9, passed through a color mozaic filter 10, and focused on the photo-electric conversion surface of a CCD 11. The CCD 11 makes photo-electric conversion of the light flux of the object 20 and gives the result to a photographing signal processing circuit 14 as a photographing signal. Further an image signal processing circuit 17 reflects the image of the object 20 stored in a visible image memory 15 and a fluorescent image memory 16 on a monitor 7, with the image due to visible light and the image due to fluorescent displayed in individual screens, in a synthesized screen, or in one screen. Thereby the light flux in the visible range, the one in the exciting light range, and the one in fluorescent range can be separated.
