Abstract
The invention provides a focus adjuster for laser beam machine which adjusts focus by detecting reflected light of a laser beam in a laser beam machine. A laser beam outputted from a laser oscillator deviceis reflected by a mirrorvia an output mirrorand introduced into a laser machining tool. The laser beam collected by a machining lensis reflected by a reflector plate Mand sensed by a reflection detector. Automatic focus adjustment is achieved by sensing output of the reflected light as well as changes in focal position due to contamination of the machining lens
