Abstract

PURPOSE:To simplify the adjusting work by incorporating a semiconductor laser, a beam splitter, and a semiconductor sensor as one body. CONSTITUTION:The semiconductor laser 41 which is incorporated into a stem together with a positive electrode post 412 and a negative electrode post 413 as one body is directly fixed to the one surface of the beam splitter 42 via a cap 414. A semiconductor sensor 45 which is incorporated into a stem together with a positive post 453 and a negative post 452 is directly fixed to the other surface of the beam splitter 42 via a cap 454. Since the laser 41, the sensor 45, and the splitter 42 are incorporated as one body, a reflecting plate can be attached to the surface A of the splitter 42 beforehand, and the positions of the laser 41 and the sensor 45 can be adjusted. Therefore, the adjusting work can be simplified.
