Unless the use of any manual line drawing or printing device, Berlinlasers 532nm green line laser alignment always makes sure of highly clear and fine green line indication at various work distances. After easy use of 5V, 9V 1000mA DC power supply, within 5mW to 100mW output power and basic use of thermal emitting system, it keeps work with highly visible green laser beam emission, highly clear and stable green line projection within long extending distance of 25 meters and high lighting etc.
This 532nm green line laser module is applying a qualified glass coated lens or separate crystal lens within 10 to 110 degree. It is a necessity to make basic measurement and experiment of technical data, after correct use of optic lens degree and output power, it assures highly clear and fine green line projection for laser cutting, sand milling, lumber machine, laser car wheel alignment system and high tech work etc.
