Said light is then passed through a half mirror 5 and an objective lens 6 and after the light is reflected by an object 7 to be examined, the light passes again through the lens 6, the mirror 5 and a half mirror 8 and arrives at an image plane 13. On the other hand, the luminous flux reflected from the mirror 8 is filtered to only the IR component by a half mirror IR filter 9, which IR light is split to luminous fluxes 11a, 11b by a prism 10 for splitting optical path and is made incident to an image sensor 12. the sensor 12 takes out the focusing signal in the positions of respectively a front focus and a rear focus with respect to the fluxes 11a, 11b. The automatic focusing is accomplished by such focusing signal.
