In order to get super clear cross line alignment at quite longer work distance than hand reaching, it would be the most wonderful experience for users to have a try of Berlinlasers 650nm red cross line laser module. It is a direct diode emission dot alignment tool, owing to its excellent use of qualified glass coated lens and import 650nm red laser diode, it is easily generating highly stable red cross line source generation from laser beam aperture part.
Employed by qualified glass coated lens with selected optic lens degree of 10, 15 and 110 degree, 650nm red cross line laser module is obtaining highly accurate 90 degree two perpendicular lines with selectable line length of 0.5 meter to 6 meters. It is not adjustable focus, however, users can still make quite easy screw of laser beam aperture part to obtain different line thickness in distance. This cross laser alignment gets wide range output power of 5mW to 100mW, which is able to work with quite clear cross line generation for laser alignment for screen printing system, laser medical treatment, military targeting and other industrial cross line use fields etc.
