In a lot of industrial precise line measuring work fields, no matter it is pointing at close or long distance, it is operating easy and quick with a high purity light emitting tool, such as a Berlinlasers 635nm red line laser module. It gets less than 1mrad laser beam divergence and special Tem00 laser beam mode. Cooperating with a metal heat sink cooling system, it gets highly stable performance and extremely fine red line emission in long lasting use.
The special use of separate crystal lens assures non Gaussian distribution red laser light emission from a 635nm red laser line generator. It keeps work with high uniformity and fine red line emission, and the same line brightness from middle part towards both ends. Within wide fan angles of 10 to 93 degree, it gets highly straight red line within 0.5 meter to 6 meters, and high fineness of 0.3mm at 10cm, 1mm to 2mm at 2 meters. After its freely adjusted red line fineness and line emitting direction, within the maximum work distance of 25 meters, it brings users no mistake use for lumber machine, laser cutting, sand milling, textile garment processing, stone, wood, garment processing and high tech work etc.
