445nm Blue Line Laser Module Review In various industrial precise line measuring work fields, not easy to reach with manual line drawing device, it makes even better job with a Berlinlasers 445nm blue line laser module within 50mW to 100mW. It projects intense and powerful blue laser light from a 445nm blue laser diode. It is getting a bit shorter wavelength than 473nm blue DPSS laser, after basic use of a metal heat sink cooling system, it just gets 40% improvement of laser beam stability, and highly clear blue line emission in long lasting use. The special use of a qualified glass coated lens is cooperating with up to 24 hours aging preventing and beam stability tests. This blue laser line generator gets wide fan angles of 10 to 110 degree, which projects high transmittance blue laser light, and highly clear and fine blue line emission. When it gets freely adjusted blue line fineness and line emitting direction, it brings users the lowest price and the most stable blue line generation for both industrial and high tech precise line measuring fields perfectly. https://www.berlinlasers.com/445nm-50mw-...ne-laser-module
