How to make precise use of 5mW to 100mW 650nm red laser diode module?

What is an efficient job to make precise enough dot alignment? It might be processing at quite long work distance, not easy to reach with manual dot projecting tool, but substituting by Berlinlasers 650nm red laser diode module. It projects highly intense and visible red laser beam from a 650nm red laser diode within 5mW to 100mW. After easy connects with 5V, 9V 1000mA DC power supply, it enables long lasting and no decay light red dot alignment in constant use.
Employed by a qualified glass coated lens and glass window inside durable metal housing tube, after up to 24 hours beam stability and aging preventing test, this 650nm red laser diode module is always working well with highly clear and stable red dot alignment, no effect by moisture or dust as well. After its correct use of output power and freely adjusted laser beam focus, it gets increasing accuracy and low production cost dot alignment in long lasting use perfectly.
Applications: industrial precise dot alignment, drilling system, laser marking, laser engraving, red laser sight and high tech
