PURPOSE:To execute easily the adjustment, by constituting so that a holding device of a reflector rotates and is made to press-contact on the spherical surface centering around the intersection point of optical axes of two lens systems, and also the optical axes are not shifted when the optical axes of both lens systems are made to conform with each other. CONSTITUTION:In one hollow part of an optical device body 10 having the first and the second lens systems 1, 2, a spherical seat 3 is formed on the spherical surface centering around an intersection point P of optical axes of both lens systems, and to its spherical seat 3, a correcting member 4 being a holding device is made to press-contact. To the rear end part of the correcting member 4, a reflector 7 is fixed at a prescribed angle, and the right end part of the correcting member 4 in its upper part becomes an optical transmitting part 4d. When adjusting the reflector 7 to the optical device 10, 4 screws 5, 6 for fixing the correcting member 4 are loosened, the direction of the reflector 7 is adjusted by rocking the correcting member 4 along the spherical seat 3, and thereafter, the correcting member 4 is fixed to the device body 10 by clamping the screws 5, 6. |
