PROBLEM TO BE SOLVED: To provide an optical switch using tilt mirrors which enable easy mounting of an optical component by simplifying the constitution and realize a short space propagated distance of an optical beam. SOLUTION: This optical switch using tilt mirrors is provided with a collimator array 1 and a collimator array 2, in which the input part and the output part are arrayed and integrated, and a shift-type folding mirror 3, with which the optical path of incident light is shifted in a prescribed direction and the light is folded and emitted, and is constituted, in such a manner that the light which is made incident to the input part 1A of the collimator array 1 is reflected at the input part 2B of the tilt mirror array 2, is sent to the shift-type folded mirror 3 by changeover of the optical path, and the light which is shifted and folded by the shift-type folding mirror 3 is reflected at the output part 2B of the tilt mirror array 2 and is outputted from the output part 2B of the collimator array 1. |
