What is the most efficient solution for make highly clear cross line generation in distance? Under the assistance of Berlinlasers 650nm red cross line laser module and easy connect with a DC input power supply, it gets continuous red cross line source emission in distance effectively. It is an industrial stabilized laser device, owing to quite nice equipment with a metal heat sink cooling system inside aluminum alloy housing tube, this red cross laser ensures excellent thermal emitting and the most stable red cross line source emission in distance effectively. This 650nm red cross line laser module gets good equipment with qualified glass coated lens. It is in need to generate different cross line length in use. Glass coated lens gets selected optic lens of 10, 15 and 110 degree, it gets different cross line length within 0.5 meter to 6 meters in use. When users are making quite easy adjustment of laser beam focus and cross line targeting direction, this red cross laser gets the most satisfied results for any industrial precise device manufacturing works perfectly. http://www.berlinlasers.com/650nm-red-cross-line-laser-module
