How to make efficient use of glass lens 445nm blue line laser module precisely?

In process of high precision and high stability line alignment at different work distances, it always makes an efficient job with a Berlinlasers 445nm blue line laser module. It emits intense blue laser light directly from a 445nm blue laser diode. Employed by cooling system and APC, ACC driving circuit board, this direct diode emission made laser device just adopts quite small size tube design and enables highly reliable blue line alignment in constant use.
This laser line generator applies a qualified glass coated lens within 10 to 110 degree and glass window inside durable metal housing tube, it enables easy carrying, good thermal emitting and highly reliable blue line alignment in continuous use. It projects highly fine blue line within 0.5 meter to 6 meters. Under operation with correct output power and optic lens fan angle, without the use of sunlight, it provides users the lowest price, long lasting and no mistake blue line generation at great distance perfectly.
Applications: industrial line alignment, laser show, laser displaying, decoration, laser medical therapy and high-tech etc
