In order to make precise enough line alignment at longer work distance, it is making good job with a high brightness beam emitting device of 50mW 532nm green laser line generator. In industrial and high tech line measuring work fields, owing to its good use of cooling system and APC, ACC driving circuit board inside its durable metal housing tube, this 532nm green laser module just adopts 26mm diameter tube, and assures highly stable and reliable green line alignment within constant work time of 8 to 10 hours. 
When 50mW 532nm green laser line generator makes the best use of separate crystal lens within 10 to 93 degree, it is emitting highly fine and uniform green line from beam aperture. The inner part of APC, ACC driving circuit board assures constant line alignment within 8 to 10 hours per day, and no laser light decay in continuous use. This 980nm infrared laser module should only be selecting with correct optic lens degree, after its proper adjustment of line fineness, it makes sure of highly precise and fine line indication at long work distance effectively.
