In order to make the most accurate dot alignment at extremely quite long work distance and quite high lighting working occasion, none of formal power made green laser pointer or other simple manual dot projecting tool can be helpful at all. However, with the assistance of constant work on the most practically used laser device, such as a high power green laser diode module, after perfect configuration with external DC input power supply and separate thermal emitting system, this high power green dot laser is always effective enough to gain highly accurate and bright green reference dot projection efficiently.
The real experience with high power green laser diode module is not the same as any formal power laser pointer. When it is getting high power up to 200mW, under generation of the most easily absorbed and the most sensitive color green laser light emission from beam aperture, unless it is used under sunlight, this green dot laser would make highly clear dot generation in distance easily. For the most important of all, according to quite easy screw of adjustable cylindrical lens, the most intense green laser light is immediately concentrated, and then generating the most accurate green reference dot projection easily.
The whole process of laser dot alignment would have to maintain good laser light cycling use. As a result, besides its basic design of thermal emitting system, high power green laser diode module is also getting the most important design part of APC, ACC driving circuit board. In continuous green reference dot projection, there is always quite powerful and intense green laser light generated from beam aperture. However, the intelligent feedback system is preventing serious electric current impacting and increasing temperature of laser tube, which is always making the best tube protection from burning out or damage.
When front part of high power green laser diode module is designed with qualified glass coated lens, under quite special design of glass window in front of beam aperture, it is keeping quite high laser beam transmittance and highly clear green reference dot projection under any moisture and dust working condition. Under continuous green reference dot projection within 8 to 10 hours per day, after quite enough time leaving for laser tube cooling down, this alignment laser is always keeping excellent laser light cycling use and extremely stable green reference dot projection in use. Whenever users are paying high attention to the most powerful laser light and wearing laser safety glasses, it achieves high security dot measurement.
