Based on the advanced 650nm red laser diode tech and a qualified optic lens inside a durable metal housing tube, it is manufactured into a professional dot measuring tool of Berlinlasers 650nm red laser diode module. It gets constant power source supply. For the most important of all, being made with an inner cooling system with different dimension tube, it gets larger space leaving for tube cooling down and ensures ultra stable red light and red dot projection in continuous use.

Basically red laser diode module is used as a dot indicator, which is working well for education, teaching and experimental demonstrations etc. It should be selected with correct output power and properly adjusted laser dot diameter, it is working well for demonstrating the propagation of light in physics classes, including rectilinear propagation, reflection/refraction, and pinhole imaging experiments. It is always selected with lower output power, thus there is no extra laser safety measure in need.
