No matter dot measurement is processing at different work distances, it is not easy to reach with a simple red laser pointer, it makes even better job for users to adopt a Berlinlasers pro red dot laser alignment. It is getting less than 1mrad laser beam divergence and special TEM00 laser beam mode, it is projecting the brightest and the most compact size red reference dot projection at various work distances.
In long lasting dot measuring works, being made with metal heat sink and APC, ACC driving circuit board, and different size tube diameter of 16mm and 26mm, this 635nm red laser diode module is keeping work with constant output power and electric current supply, and highly reliable dot emission within 8 to 10 hours. This ultra compact size tube made red laser brings users excellent dot aligning source for laser marking, laser engraving, drilling system, red laser sight and laser medical therapy work etc.
