Abstract
PURPOSE: To make easy the adjustment of the pinholes forming filters for laser beams and automate the same by using the turret plate provided with the pinholes of required different diameters on concentrical circle.
CONSTITUTION: A turret plate 4 is controlled by way of a pinhole adjusting mechanism 3 by using the continuous beam for alignment focused by the objective lens 2 of the special pinhole device 7 which is put in a vacuum state by a vacuum pump 6 and the position of the pinhole 9 of super hard metal material of the specified diameter for alignment on the same circle of the turret plate 4 is so adjusted as to align to the center of the continuous beam. Thence, when the turret plate 4 is turned by the mechanism 3, the positions of the pinholes 10W15 of the second large diameters for removing the space frequency components of the high frequency of the high output pulse laser light focused by the lens 2 are readily adjusted to the position where the pinhole 9 has been set, whereby the pinhole position alignment may be automated. Here, a pinhole 16 or the like of particularly large diameter which permits straight passage of the laser light is provided to the turret plate 4.
