Not always relying on any manual or mechanical line aligning works, in order to make quite satisfied line projection at quite long work distance, it is just substituting by advanced laser tech applying 100mW red line laser module. It is not only making advanced use of 650nm red laser diode tech, basically equipped with inner qualified glass coated lens with different fan angle, this laser line generator is projecting highly straight and fine enough red reference line projection in use. Only after its easy installation and adjustment of both beam focus and line targeting direction, it makes the most satisfied line projection at great distance effectively.
The usual use of 100mW red line laser module is continuing for quite long time, but not simply used as a simple red laser pointer. After special use of an external DC input power supply, accepting wide range electric current within 100V to 240V, it is keeping work with continuous red reference line projection. In continuous red laser line alignment work, under increasing temperature, this laser line generator still gets perfect protection from overheating and over current in continuous use. At the same time, the special use of electric wires extension also enables freely installed distance of 3 meters, which would make the most satisfied line projection onto any vertical or horizontal surface conveniently.
After advanced use of glass coated lens and quite strict laser beam stability tests up to 24 hours, 100mW red line laser module just keeps work with high linear quality red reference line projection. In constant line projection within 8 to 10 hours per day, after enough time leaving for tube cooling down, it is just able to work with excellent laser light cycling use and extremely clear red line projection in long time use. Although it is projecting formal Gaussian beam from beam aperture, however, it is enough to fulfill moderate accuracy red line projection as expected.
Whatever kind of working surface it is pointing, 100mW red line laser module is not only making highly clear line projection at great distance, but also projecting serious thermal energy and increasing temperature in use. The special use of APC, ACC driving circuit board prevents alignment laser from overheating and over current, always obtains up to 85% beam stability in continuous use. Whenever users are making constant line projection for all industrial line measuring works, in order to avoid hurt to human eyes, users should always wear correct 650nm wavelength preventing laser safety goggles and adjust red line targeting direction so as to achieve no mistake and no track line alignment constantly.
