Any time line alignment work is processing at different work distances, it is far more enough to reach until selecting a correct line measuring tool, such as a Berlinlasers 532nm green laser line generator. It projects highly visible and bright green laser light from a 532nm green DPSS laser system. Unless it is pointing under sunlight, within wide range output power of 5mW to 100mW, it provides users ideal line aligning source for all raw material processing works.
Being made with qualified glass coated lens within 10 to 110 degree, and special use of a glass window, this green line laser module is working well with highly fine and clear line emission. It gets different line lengths of 0.5 meter to 6 meters. At the same time, after basic use of output power and optic lens degree, within the maximum installed distance of 3 meters, it assures high precise line alignment for laser cutting, sand milling, lumber machine, textile garment processing and high tech work etc.
