How to make constant use of DC power 635nm red line laser module

What is the best for you to make constant line alignment at different work distances? It might be far more enough than your formal hand reaching, however, it still makes a good job to operate a high purity light emitting tool of a 635nm red line laser module. Employed by an import 635nm red laser diode and cooling system, configured with different dimension and high duration anodized aluminum alloy housing tube, it always allows easy carrying, good thermal conductivity and the most reliable red line alignment within long work time of 10 hours.
Owing to the special use of a qualified glass coated lens with 10 to 110 degree fan angles, together with strict laser beam stability tests, the genuine use of a laser line generator just allows proper use by skilled users or professionals. It enables long lasting line alignment and takes low manual labor force input. Only if ultra compact size tube made laser device gets proper installation and adjustment of laser beam focus, it gets increasing accuracy and fineness red line alignment at great distance perfectly.
Applications: lumber machine, laser cutting, saw mill, laser car wheel alignment system, laser medical therapy and high-tech
