Only according to quite easy connect with an external DC input power supply, green laser line generator is able to generate immediate green reference line on required working surface. It is not a hard job for users to operate such kind of line alignment tool. Although users are not learning a lot of real laser line alignment work, it is just need a short term treatment of basic laser safety measures and laser operating rules. When it is keeping connect with correct voltage electric power source, green laser module keeps constant green reference line targeting easily.
The inner part of glass coated lens is just a very important part for green laser line generator to get high quality green reference line targeting in distance. It is able to emit high linear quality green line at quite long work distance. At the same time, within its quite wide range optic lens degree from 10 degree to 110 degree, green laser line is available with different line length from 0.5 meter to 6 meters. Anytime users are not much sure whether real line alignment is correct or not by those of manual or mechanical line aligning tool, it is just the time to select such nice substitute of this green laser module.
Owing to quite nice design of electric wires connecting green laser line generator tail part and DC input power supply, the whole process of laser line alignment allows free installation and adjustment within 0.5 meter to 3 meters, which has just made the real line targeting easy and convenient in any kind of industrial machinery processing works. At the same time, once users are not simply making line alignment at quite close distance, but just making line alignment at long distance and high lighting with quite high power up 50mW. In order to assure high security line alignment all the time, it is just a key point for users to wear a pair of laser safety glasses until getting safe line aligning all the time.
