The design of green cross line laser module is not the same as a simple laser pointer, which is just required to work with a quite complex laser light in shape of two perpendicular lines, and still keeping work for a quite long time. Inside its 16mm or 26mm diameter tube, there is just enough space reserving as its cooling system. The metal heat sink cooling system is not only getting at least 5 times better thermal emitting than formally used air or water cooling, but also making perfect configuration with aircraft used aluminum alloy housing, in process of continuous cross line alignment work, this green laser module gets superior nice thermal conductivity, and then assuring stable and reliable enough cross line targeting within 8 to 10 hours a day.
Anytime green cross line laser module is designed with different size laser tube, and external DC power source, there is just larger space reserving as its cooling system. Once it is workable with other machine or device, it will generate noncontact green vertical and horizontal laser lines with accurate 90 degree, which is just a super wonderful choice for users to make accurate cross aligning for laser alignment for screen printing system, military targeting weapon, heat transfer machine or other laser medical treatment devices. In order to maintain reliable performance and good cycling use of green cross line laser source, green laser module should be cooling down after a few hours continuous works.
According to quite easy installation of green cross line laser module within wide installing distance of 0.5 meter to 3 meters, no matter what kind of working surfaces, the real cross line alignment work just gets no barrier caused by work distance, height, corner, hard reaching places for human hands or mechanical tools. Even though green cross line laser source is pointed at quite long distance, in order to get safe measurement, users should just be remembering to wear a pair of laser safety glasses. Only after correct choices of output power and optic lens degree, a proper installed green laser device just gets no danger work all the time.
