LASER IRRADIATION DEVICE AND METHOD OF DIAGNOSING THE HEALTH OF A LASER IRRADIATION HEAD

摘要

A laser irradiation device comprises a laser oscillator, a laser irradiation head that performs laser processing by directing the laser beam onto the region to be processed; and a transmission mechanism that gets the laser beam through emitted from the laser oscillator to the laser irradiation head. The laser irradiation head comprises: a laser beam adjustment unit that adjusts the laser light to create a laser beam; a protective glass window arranged in an emission region that emits the laser beam; a reflection mechanism that gets the laser beam through and reflects visible light; a wavelength-dependent optical screening mechanism that cuts off light of a wavelength region other than visible light from the light that is reflected by the reflection mechanism; an image adjustment lens unit that adjusts an image comprising visible light that is input from the wavelength-dependent optical screening mechanism; an image pickup camera that inputs an image; and an image processing mechanism that processes the image.

主权项

1. A laser irradiation device having
(1) a laser oscillator that generates a laser beam; (2) a laser irradiation head that performs laser processing by directing a laser beam generated by said laser oscillator onto a region to be processed; and (3) a transmission mechanism that gets said laser beam through emitted from said laser oscillator to said laser irradiation head, wherein said laser irradiation head comprises: (a) a protective glass window arranged in an emission region that emits said laser beam of said irradiation head onto said region to be processed; (b) a reflection mechanism, provided within said irradiation head, that gets said laser beam through and reflects at least visible light, of reflected lights from said region to be processed; (c) an image pickup camera that inputs said light reflected by said reflection mechanism; and (d) an image adjustment optical system, provided between said reflection mechanism and said image pickup camera, whereby a focal point position of said image pickup camera can be changed over to a position of at least said protective glass window and said region to be processed.
