In order to make the clearest line alignment at quite long work distance, usually out of hand reaching, it is becoming the most popular job for users to make use of a 445nm blue line laser module. It projects moderate brightness blue laser beam from 445nm blue laser diode. Although it is not as bright as a 473nm blue DPSS laser, however, after proper equipment with the best quality separate crystal lens and thermal emitting system inside durable metal housing tube, this laser line generator is not only projecting highly intense blue laser light, but also generating highly clear and accurate blue line alignment at quite long work distance. 
Not seriously relying on manual labor force input, 445nm blue line laser module is operating easily after its connects with an external DC power supply. It is operating without any seriously relying on manual line printing work. Employing import 445nm blue laser diode within 50mW to 100mW, it is just adopting 5V, 9V 1000mA DC power supply as its electric power source. It is projecting highly powerful and intense blue laser beam at several miles far away, but also generating highly clear and fine enough blue line alignment as long as 25 meters and other formal lighting working occasions.
When line alignment is processing onto multiple working surfaces, either it is pointing for industrial and high tech, 445nm blue line laser module is pointing with different line lengths and line finenesses. It is projecting formal brightness blue laser beam from 445nm blue laser diode. Even though it gets high output power up to 50mW to 100mW, however, it is adopting quite small size tube diameter of 16mm. Only if blue laser line generator leaves enough space for inner cooling system, it is achieving perfect laser light cycling use, and extremely clear blue line alignment for both long distance and long time use. 
Owing to the use of separate crystal lens, 445nm blue line laser module is getting even more brighter and visible blue laser beam and blue reference line at quite long work distance. At the same time, even though blue line is pointing at quite long work distance, it is still keeping work with the same brightness from middle part towards both ends, and obtaining extremely fine blue line alignment at quite long work distance. When industrial alignment laser makes quite easy screw of adjustable focus optic lens, after high speed blue laser light focusing, it just achieves the finest blue line indication. At the same time, when users are aware of any thermal energy hurt to eyes and wearing correct laser safety goggles, it always makes safe and no decay light line alignment in all occasions effectively.
