Abstract
PURPOSE:To avoid the vignette at the periphery of the photographing viewfield regardless of the size of the photographing lens, by inserting the photographing lens and the relay lens between the object reflecting optical system and the image rotational optical system and then mounting the image-formation lens onto the TV camera. CONSTITUTION:The viewfield beams which are introduced in sequence by the rotation of motor 3 and via object mirror 1 form the image once via photographing lens 9, and are then corrected into the parallel luminous fluxes via field lens 10 and relay lens 1 to be introduced to image rotational prism 7. Thus the viewfield image inverted by mirror 1 is inverted again by prism 7 to be the upright image. This upright image is then put into lens 12. Accordingly, the viewfield range to be photographed by TV camera 8 becomes in agreement completely with the viewfield which is decided by lens 9. And then the zoom lens is used for lens 9, and as a result the viewfield image in a comparatively wide range or the increased viewfield image can be projected when necessary on the TV screen accurately and with no vignette.
