Abstract
A laser irradiation device in which laser light is adjusted to create a laser beam, including a protective glass window arranged in an emission region that emits the laser beam; a reflection mechanism that passes the laser beam 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; image pickup camera configured to capture the visible light reflected with the reflection optical element; and an image adjustment lens unit that adjusts an image in the visible light that is input from the wavelength-dependent optical screening mechanism. The wavelength-dependent optical screening mechanism is provided between the reflection optical element and the image camera.
