If line measuring work is processing at different work distances, it might be far more enough than formal hand reaching, however, it should be a quite nice beginning for users to operate a high density beam emitting tool of a 520nm green line laser module. It applies advanced 520nm green laser diode tech and a qualified optic lens with wide fan angles inside a high duration metal housing tube. In practical precise line positioning work fields, within quite long work distance and other formal lighting working occasion etc, this accessory part of a laser line generator enables quite easy installation, quick reaching and good direction green line alignment for a lot of raw material processing works constantly. 
When 520nm green line laser module applies an import 520nm green laser diode within 5mW to 50mW as its beam emitting source, it always makes easy reaching and no barrier line indication for a lot of raw material processing works. It applies an inner metal heat sink cooling system inside a durable anodized aluminum alloy housing tube, whatever kind of working surface it is pointing, this laser line generator always gets good thermal emitting and thermal conductivity, and ultra stable and reliable green line alignment within long lasting line positioning work of 10 hours per day. For the most important of all, when it gets proper use by professionals or skilled users, after basic obeying of laser safety issue, it still brings users quite satisfied line positioning results for all raw material processing works constantly.
According to basic measurement and experiment of desired line length, line fineness and work distance, this 520nm green line laser module always correct use of output power and optic lens fan angle. It emits high quality Gaussian beam from a qualified glass coated lens within 10 to 110 degree fan angles, thus projects high linear quality and straight green reference line within 0.5 meter to 6 meters length in use. In a lot of industrial and high tech precise line positioning work, this accessory part of a laser line generator just makes good job for laser cutting machine, saw mill, lumber machine, textile garment processing, laser medical therapy and high tech work etc.
Within quite a long work distance and other formal lighting occasion etc, with the assistance of a laser alignment mounting bracket, this Gaussian beam 520nm green line laser module always enables quite easy carrying and quick reaching of green line projection onto any vertical or horizontal surface. It makes sure of a noncontact and no mistake line positioning results for all industrial and high tech work fields. Whenever green alignment laser makes proper installation and adjustment of both of laser line fineness and line emitting direction, it just brings users high precision and high stability use for all working occasions effectively.
