With the assistance of 650nm red laser diode tech and constant technical innovation of the most practically used cross line alignment device, laser tech engineer has just made super great work of 50mW 635nm red cross line laser module. It is performing with the purest red laser light. In any industrial and high tech cross line measuring work fields, after basic use of qualified glass coated lens with different fan angles and good use of cooling system inside highly durable metal housing tube, this red cross laser alignment just assures the most complex two perpendicular lines with accurate 90 degrees in distance. \r\n\t\t\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\t\t\r\n\t\t\t\t\t\t\t\t\tWhen 50mW 635nm red cross line laser module is adopting an external electric power source, different from a formal manual or mechanical cross line alignment tool, it always makes easy and quick cross line generation. After the use of an external 9V 1000mA DC power supply, it is just able to work with continuous red laser beam emission, and highly clear red vertical and horizontal line generations as long as 25 meters. In occasion that there is increasing temperature of laser tube, however, this red cross laser just allows the maximum cross line projection within 8 t 10 hours. It is just allowing the maximum installed distance of 3 meters, and convenient cross line alignment without any barrier and mistake in continuous use.Any time 50mW 635nm red cross laser module is passing through quite strict laser beam stability tests up to 24 hours, after special use of glass window in front of laser beam aperture, it is performing without any laser light decay or blur in continuous use. It is generating high transmittance red laser light, and allowing highly clear red cross line generation within the maximum work distance of 25 meters. Under operation with freely selected glass lens fan angles of 10 degree to 110 degree, after correct use of glass lens degree, it makes sure of satisfied measurement for laser alignment for screen printing system, military targeting, laser medical therapy and other high tech work etc.With the assistance of laser alignment mounting bracket and extending electric wires, 50mW 635nm red cross line laser module enables easy mounting onto other machine or device. Noncontact red cross line laser source is easy to reach any working surface, also leaving no track in practical use. For the most important of all, this industrial alignment laser allows easy adjustment of laser beam focus and quick laser light concentration, it just achieves the finest red cross line source generation in continuous use. Any time users are paying high attention to laser safety issue and wearing proper laser safety goggles, without eye exposure to laser beam aperture, high power red cross laser makes no danger and no mistake measurement perfectly.
