Abstract
A structure of an optical path for laser range finding includes a main body and a light-emitting unit assembled in the main body. The main body has a transmitting channel, a receiving channel and a calibration channel. The light-emitting unit is assembled in the transmitting channel. The light-emitting unit emits an external optical beam and an internal optical beam. The external optical beam is emitted through the transmitting channel. The internal optical beam is emitted to the receiving channel via the calibration channel. An included angle is defined between the external optical beam and the internal optical beam. A receiver is mounted in the receiving channel. Under this arrangement, the external optical beam and the internal optical beam do not interfere with each other.
