In process of highly clear and stable dot alignment at different work distances, it is operating easy and quick with a Berlinlasers 650nm red laser diode module. Available with an import 650nm red laser diode within 5mW to 100mW and metal heat sink cooling system inside 16mm and 26mm diameter metal housing tube, it gets superior nice thermal emitting and highly stable red dot projection in long lasting use.
This red dot laser alignment adopts a 5V, 9V 1000mA DC power supply. It gets no need to make battery change, but gets highly stable red dot projection within 8 to 10 hours. Unless it is pointing under sunlight, after correct use of output power and freely adjusted laser beam focus, it gets increasing accuracy and brightness red dot projection for industrial precise dot measurement, drilling system, high tech and lab experiment work etc.
