PROBLEM TO BE SOLVED: To provide an optical switch having a converging optical element. SOLUTION: The optical switch includes an input collimator for receiving, collimating and outputting an input light beam, an output collimator, an input mirror disposed so as to receive the light beam from the input collimator, an output mirror disposed so as to receive the light beam reflected by the input mirror and reflect the light beam into the output collimator and the converging optical element disposed so as to receive the light beam reflected by the input mirror and reflect the light beam into the output mirror.
