If users are trying to get super clear dot alignment on multiple working surfaces, it would be the most marvelous experience for users to make good use of Berlinlasers red dot laser alignment. It is using import 650nm red laser diode as its laser beam emitting source, owing to its mature laser diode tech and mass production, this red laser alignment is not only able to work with highly stable red reference dot targeting, but also available with low production cost.
This red dot laser alignment is just a very economic solution for those of industrial precise machinery processing work fields. It is working immediately after its easy connect with DC input power supply. No matter it is being made with 16mm or 26mm diameter tube diameter, it is getting the best thermal emitting from its metal heat sink cooling system and aluminum alloy housing. Users can use it freely for multiple work fields, including laser marking machine, drilling system, military targeting, laser engraving machine etc.
