Abstract
PURPOSE:To intercept a laser beam quickly and precisely by providing a shutter for intercepting the laser beam to a turning shaft intersecting orthogonally with the optical axis of the laser beam. CONSTITUTION:A shutter 4 is mounted to the leading end of a turning shaft 3 intersecting orthogonally with the laser beam L from a laser 1. If the shutter 4 is turned by theta in an arrow direction by a driving source 2, the half of the laser beam L is reflected by falling to the end face of the shutter 4 and the other half is reflected by the inside wall surface of a slit 5, whereby it passage to a rectilinear direction is intercepted. If the width of the laser beam L is set at 1mm., the width of the slit 5 at 1.5mm. and the width of the shutter 4 at 5mm., the rotating angle theta is a small value of about 16.6 deg.. Since the angular moment is small, the laser beam is intercepted quickly precisely.
