In process of quite accurate line alignment in distance, it is just a full of challenge job to obtain quite satisfied line alignment as expected. However, on basis of the good use of a high brightness green line laser module, on basis of its middle wavelength of 532nm among all visible laser devices, this laser line generator is just obtaining the most easily absorbed green laser light in distance. Unless line alignment is being used under sunlight, a correct output power made line laser alignment tool is always effective enough to gain highly accurate line instruction as expected.
In process of long distance line alignment work, owing to the design with separate crystal lens, green line laser module is just generating non Gaussian beam distribution in distance. When line alignment is processed at quite long distance, it is still keeping high uniformity red laser line targeting. Red line is just keeping the same line brightness at quite long distance, thus it it always getting improving line aligning accuracy in current precise device manufacturing works. When separate crystal lens is available within 5 degree to 93 degree, it is getting different line length from 0.5 meter to 6 meters, and then making sure of the highest level of accuracy line alignment for all high tech and industrial line aligning works marvelously.
According to special design part of APC, ACC driving circuit design, whatever kind of working surface, green line laser module is getting the most efficient preventing of electric current impacting, and supporting highly stable alignment laser line targeting in long term use. Without spending extra time on battery changing, the real line alignment should only ask users to select correct operating voltage made electric power source, and then obtaining the clearest alignment laser line targeting in long term use. After proper selecting of 532nm wavelength preventing laser safety glasses and correct adjustment of line targeting direction, this laser line module would always get no mistake measurement efficiently.
