Whenever users are looking for the most accurate line positioning result, especially in occasion of quite long distance, it is just a very nice experience to try Berlinlasers 50mW green line laser alignment. It gets basic use of inner metal heat sink cooling system inside durable aircraft used aluminum alloy housing tube. Inside 26mm diameter metal housing, green laser module achieves superior nice thermal emitting and increasing stability green line projection continuously. The advanced use of high quality glass coated lens or separate crystal lens is perfectly avoiding laser light decay or dim in continuous use. When users are getting basic measurement of line length, line fineness and work distance, only if 50mW green line laser alignment gets correct measurement, it would get correct selection of fan angles. In addition, after its proper installation, users can also make easy screw of adjustable focus optics, it achieves high level of accuracy line projection at long distance.
