When line measuring work is processing at quite long work distance, it is not easy to reach with manual line drawing device, but making even better job to operate a Berlinlasers 532nm green laser line generator. When it projects highly visible green laser beam from a 532nm green DPSS laser system, after selecting high power up to 50mW to 100mW, it assures highly visible and clear green line emission within long extending distance of 25 meters and high lighting etc.
This green line laser module applies a qualified glass coated lens within 10 to 110 degree. Only after correct use of optic lens degree and output power, it just provides users ideal line aligning source for lumber machine, laser cutting machine, sand milling, textile garment processing and high tech work etc.
