PURPOSE:To eliminate the need to align optical axes with each other and to improve the handling by forming a united structure which enable laser distance measurement and noctovision and aligning an optical axis for the noctovision and the optical axis for the laser distance measurement equally with the optical axis of an objective. CONSTITUTION:A noctovision function part 2 consists of a noctovision tube, an ocular, a power source, etc., and receives noctovision light 10 incident through the objective 1 to display a noctovision function. A laser distance measuring function 3 has a projection port 3a for emitting laser light 9 into the objective 1 and an incidence port 3b through which target reflected light 11 from the objective 1, and the distance measuring function is displayed based on the reflected laser light 11 inputted to the incidence port 3b. The objective 1 consists of a reflecting mirror 6, a subordinate mirror 4, a dichroic mirror 7, and a main mirror 5.
