No matter line aligning work is processing at close or long distance, it makes good job with a Berlinlasers 635nm red line laser module within 5mW to 100mW. The advanced use of a metal heat sink and import 635nm red laser diode are assuring good thermal emitting and highly stable red line alignment in long lasting use.
Being made with the best quality separate crystal lens within 10 to 93 degree, and special use of a glass window inside high duration metal housing tube, this red laser line generator is working well with highly straight and fine red line within 0.5 meter to 6 meters. It enables freely adjusted laser beam focus and laser line projecting direction, within the maximum work distance of 25 meters, it provides users the highest level of accuracy line alignment for laser cutting, sand milling, lumber machine, laser car wheel alignment and high tech work etc.
