In special need of highly clear and accurate dot measurement at quite long work distances, none of manual dot projecting tool can reach easily. It is not the end for users to develop a quite practically use device, such as a 150mW high power green laser diode module. It is projecting the brightest and the most sensitive color green laser light from a middle wavelength of 532nm green DPSS laser system. Under operation with special use of separate thermal emitting system and constant power source supply, it just achieves excellent laser beam stability and highly clear green reference dot projection at long work distance and high lighting working occasion etc.
Comparing with any other visible laser devices, 150mW high power green laser diode module is getting middle wavelength of 532nm. It projects the most sensitive color and the easiest absorbed green laser light from laser beam aperture. In occasion that it gets low laser beam divergence of less than 1mrad and special TEM00 laser beam mode, even though dot aligning work is processing at quite long work distance, it still keeps work with ultra compact size and the brightest green reference dot projection at long extending work distance.
The special use of a separate metal heat sink cooling system has just made high power green laser diode module different from a formal low power laser device. There is always quite powerful and intense green laser light emission from laser beam aperture. However, after configuration with high duration anodized aluminum alloy housing tube design, it achieves superior nice thermal conductivity, and highly reliable green reference dot projection under any other harsh working occasions, such as mechanical moving or shocking, and wide range operating temperature as well.
Being made with the most important design of APC ACC driving circuit board, in long lasting dot measuring work, 150mW high power green laser diode module is working well with constant green laser beam emission and green dot projection. There is increasing temperature and serious electric current impact, however, within constant work time of 8 to 10 hours per day, this alignment laser still gets perfect protection of itself from burning out or damage, and long serving lifetime of more than 8,000 hours. For the most important of all, only if users are paying high attention to powerful green laser radiation and thermal energy hurt to human eyes, without any eye exposure to beam aperture, it just assures easy and secured dot generation in all application fields constantly.
