Anytime there is quite serious need of highly accurate dot alignment at quite long work distance than formal hand reaching, it would be quite hard work until the time users are getting the use of a 515nm green laser diode module. It is available with quite shorter wavelength than 532nm green DPSS laser, owing to excellent direct diode emission and basic equipment of metal heat sink cooling system, it is just getting improving laser beam stability, and obtaining highly stable green reference dot targeting in long term use.
Supported by 3V or 8.4V DC input power supply, 515nm green laser diode module is workable with wide range output power of 5mW to 50mW, which is easily obtaining highly clear and bright green reference dot targeting on various targeting surfaces. This adjustable focus green laser device is able to be adjusted from laser beam aperture, and then achieving highly clear dot alignment easily. After quite easy installation and operation, this green laser module assures the clearest dot positioning result for laser medical treatment, military targeting, high tech and lab experiment etc.
