The creation of 515nm green laser diode is no doubt a great technical innovation of laser diode tech. When it is made into a real 515nm green line laser alignment, the direct diode emission has just made the real line aligning work maintain even higher stability and reliability in long term use. According to its easy configuration with glass coated lens or separate crystal lens, forest green laser line is keeping quite high linear quality, and high line straightness. This high stability 515nm green laser module is also getting clear line instruction for formal industrial line aligning and high tech work fields as well.
