Title:
LASER PROCESSING HEAD, OPTICAL FIBER INSPECTION DEVICE, AND OPTICAL FIBER INSPECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/050023
Kind Code:
A1
Abstract:
A laser processing head (20) comprises: a collimator lens (23) for converting laser light (70) into parallel light beams; a condensing lens (24) for condensing the laser light (70) converted into the parallel light beams; a casing (21) in which the collimator lens (23) and the condensing lens (24) are housed; a wavelength selective mirror (25) which is provided between the collimator lens (23) and the condensing lens (24), and which transmits the laser light (70) but reflects light having a predetermined wavelength different from the laser light (70); and a transmissive window located at a position at which the light having the predetermined wavelength is transmitted and at which a laser light exit end surface (61) of an optical fiber (60) can be optically observed through the wavelength selective mirror (25).
