  • Publication number: 20220021184
    Abstract: A light source device includes a semiconductor laser that has a first end surface and a second end surface parallel to each other and forming a first resonator, and an optical system that is disposed on an optical path of laser light emitted from the semiconductor laser, that forms a second resonator with the second end surface of the semiconductor laser, and that has a reflection characteristic in which a reflectance with respect to light having a previously specified wavelength width centered at a specified center wavelength of the semiconductor laser is higher than the reflectance of the first end surface.

  • Patent number: 11175458
    Abstract: A multi-fiber connector fiber-optic measurement device identifies a polarity type and measures an optical power of a multi-fiber connector fiber-optic patch cord. The device includes: a beam splitter that splits light from the multi-fiber connector fiber-optic patch cord into a plurality of lights; a first optical sensor that receives one of the lights split by the beam splitter and outputs a first signal according to the received light; a second optical sensor that receives another of the lights split by the beam splitter and outputs a second signal according to the received light; and a signal processor that calculates the optical power based on the first signal and identifies the polarity type based on the second signal.

  • Patent number: 10499551
    Abstract: An electronic component mounting system is disclosed. An elapsed time acquiring section acquires an elapsed time from printing onto circuit board by solder printer. A raising and lowering operation changing section changes raising and lowering operation of component holding tool based on the elapsed time from printing acquired by the elapsed time acquiring section. A mounter mounts an electronic component on the solder printed on circuit board by performing raising and lowering of the component holding tool at the raising and lowering operation changed by the raising and lowering operation changing section.
