Claims

[Claims for Utility Model Registration] 1. Disposed facing the output surface side of the image tube,
A lens system that derives the output optical image as a parallel light image, an aperture that introduces the light beam derived by this lens system into the interior, and an aperture that sends it to a monitoring camera and a recording camera, An image intensifier output image splitter consisting of a dark box housing a half mirror that divides the amount of light introduced into the interior from the aperture on the lens system side into the optical axis direction of the lens system and the direction orthogonal thereto. In the optical device, the half mirror is held so as to be tiltable so that it can take a posture parallel to the optical axis of the lens system and a posture inclined at 45 degrees with respect to the optical axis, and An aperture is provided at least on the surface facing the aperture on the lens system side and on two opposite side surfaces parallel to the tilting axis of the half mirror, and the aperture facing the aperture on the lens system side is provided with a full inner surface. A light-shielding lid or a half-mirror lid that has been treated with a reflective mirror surface can be attached and removed, and a light-shielding lid with a blackened inner surface can be attached and removed to one of a pair of opposing openings that are parallel to the tilting axis of the half mirror. An image intensifier output image splitting optical device characterized in that it is attached to an image intensifier. 2. An image intensifier output image splitting optical device according to claim 1, in which the tilting axis of a half mirror housed in a dark box is rotatable around the optical axis of the lens system. .
