Not always relying on any manual dot aligning works, in special need of highly clear dot alignment at great distance, it is not helpful at all to only relying on formal low power laser device or mechanical dot aligning device. When laser tech engineer is making great technical innovation of high power 200mW green dot laser module, it would become quite easy and efficient solution. It leaves separate thermal emitting system and constant electric power source from DC input power supply, 532nm green laser alignment assures efficient thermal conductivity and extremely clear and stable green dot projection in long time use.
The usual dot alignment with 200mW high power green dot laser module would have to continue quite long time dot projecting work. It is requiring to work for quite long time, but not just limited for temporary dot positioning works. After proper use of 12V 1000mA DC input power supply, accepting wide range electric current within 100V to 240V, it is applying for various working environments, and also keeping continuous green dot projection. It is requiring to work for quite long time. However, in practical green laser dot alignment work, only if there is quite enough time leaving for tube cooling down, it is accepting operation within 8 to 10 hours per day and maintaining up to 85% beam stability in continuous use.
After advanced use of glass coated lens, even though dot alignment is processing at great distance, high power 200mW green dot laser module still keeps work with high beam transmittance and highly clear green dot projection at great distance. The special use of glass window in front of laser beam aperture makes perfect protection of green laser alignment from dust and moisture working condition, such as rain, water or fog etc. For the most important of all, after quite easy adjustment of laser beam focus, it makes the most efficient laser light concentration and extremely clear green reference dot projection in distance immediately.
On basis of the most advanced use of APC, ACC driving circuit board, even though high power 200mW green dot laser module makes immediate tube temperature increasing, however, it still gets efficient protection from burning out or damage in constant dot alignment work. Unless it is making dot projection under sunlight, alignment laser is able to make highly clear dot indication for both great distance and high lighting occasions. Every time users are aware of powerful green laser radiation and hazard to human eyes, users should try to wear laser safety glasses and avoid eye exposure to beam aperture until achieving safe and clear measurement effectively.
