If there is quite serious need of highly accurate cross line generation in distance, it would be quite nice solution for users to make use of Berlinlasers green cross laser alignment. It is employing quite high quality glass coated lens, available with selectable optic lens degree of 10, 15 and 110 degree, on basis of its high linear quality and high line straightness, this green laser module is workable with quite clear and accurate cross line alignment for laser alignment for screen printing system, military targeting, laser medical treatment device etc.
On basis of very easy connect with DC input power supply, the real cross line generation with green cross laser alignment has no need to make battery change and also obtains larger space reserving as thermal emitting system. This 532nm green laser module is available within 5mW to 100mW, unless sunlight working occasion, it is able to get extremely clear and accurate cross line generation within maximum work distance of 25 meters. Users should only install this cross line laser on correct place, only if it is properly adjusted and installed within 0.3 meter to 3 meters, it would just make sure of high accuracy cross line generation on all targeting surfaces effectively.
