In any type of ultra clear and fine line indication at a longer distance than formal hand reaching, factory workers and engineers would prefer to operate a Berlinlasers 532nm green laser line generator. It gets low beam divergence and special TEM00 beam mode, equipped with a qualified glass coated lens within 10 to 110 degree, it generates highly fine and straight green reference line within 0.5 meter to 6 meters. Only after its proper installation and adjustment of green line fineness and emitting direction, it makes no mistake and no barrier line indication for all industrial fields covering laser cutting, saw mill, lumber machine, textile industry, medical therapy and high tech fields etc.
