Whenever I am fallen into difficult of getting a very low powered laser dot measuring tool, I have just found this 5mW 650nm red dot laser alignment from Berlinlasers.com online shop. It is just a Class IIIa red laser module, but it is just workable for all industrial laser dot alignment and positioning work.

This 5mW red dot laser alignment is very low price, stable and reliable. It is just a very nice industrial laser dot worth to own.[/size]
