Infrared laser module always gets super wide application in IR laser light illumination working fields. It always makes the best use of its high superiority of high luminous efficiency and high light intensity. As a result, when 808nm infrared laser module is manufactured into laser alignment system, it can get especially high photo-electro transition rate of as high as 80%. In various kinds of industrial laser dot, line, cross line alignment work, this advanced infrared laser alignment can get the most satisfied measuring result in all occasions efficiently.
