Under operation of ultra clear, fine and precise cross line indication for teaching and research demonstration, professionals would prefer to apply a Berlinlasers 650nm red cross line laser module. It combines an import 650nm red laser diode and a qualified optic lens inside a different dimension metal housing tube, after connects with DC power supply, it enables long operating time lasted red cross line projection and good laser beam stability in continuous use.
Cross line laser module adopts compact size tube design, allowing easy installation and adjustment of both of cross line thickness and emitting direction. After its correct use of output power and optic lens fan angle,and basic laser safety measurement taking, the red cross lines intuitively project the coordinate system for teaching demonstrations in university physics laboratories, optical principle training, and geometric coordinate simulation, simplifying the experimental teaching process.
