Highly Straight 660nm Red Line Laser Module for Machinery Processing Works Unless the use of any prior line drawing or printing works, the adoption of a Berlinlasers 660nm red line laser module makes sure of ultra fine and straight red reference line projection from beam aperture. It applies an import 660nm red laser diode and a qualified glass coated lens within 10 to 110 degree fan angles inside a durable metal housing tube. Owing to its superior nice heat dissipation, it enables good laser beam stability, long term lasted red line projection for multiple industrial machinery processing works. Being made with ultra compact size tube design, laser line generator is operated as an accessory part of machinery manufacturing works. It is used for positioning lines on cutting machines, bending machines, and welding machines to assist in precise cutting and bending of sheet metal and pipes, avoiding processing deviations. Not limited by long distance or harsh working environment, it also makes good job for marking processing baselines in grinding and milling machine operations to improve the machining accuracy of parts. https://www.berlinlasers.com/glass-coated-lens-660nm-red-line-laser-module https://www.berlinlasers.com/oem-lab-lasers/laser-line-generator
