650nm Red Cross Line Laser Module with Glass Coated Lens What is the best job for users to make clear and fine enough cross line alignment? It is a quite complex job for users to get ideal cross line aligning accuracy as expected. Under operation of constant technical innovation of 650nm red laser diode tech and qualified glass coated lens with different fan angles, laser tech engineer has just designed a quite practically used device of red cross line laser module. On condition that it gets constant power source supply and good use of thermal emitting, configured with ultra compact metal housing tube, this cross laser alignment just achieves high level of accuracy and high stability red cross line generation onto a lot of working surfaces constantly. https://www.berlinlasers.com/635nm-red-cross-line-laser-module
