If users are not much sure of how to make precise and clear line indication at different work distances, it might be far more enough to reach with any prior line drawing work at all. At the same time, in order to avoid serious relying on any manual labor force input, it just becomes a good job for users to operate a highly intense beam emitting tool of a 650nm red line laser module. On condition that it applies a qualified optic lens with different fan angle inside a high duration metal housing tube, once it gets proper use by skilled users, this laser line generator brings users long lasting and long distance extending red line alignment for all application fields.
Being made with the best quality separate crystal lens within wide fan angles of 10 to 93 degree, this 650nm red line laser module just gets even better performance than formally used glass or plastic coated lens. It is performing well within non Gaussian distribution red laser light source emission from laser beam aperture. In addition, either red line is pointing at close or long distance, it still gets the same line brightness from its middle part towards both ends. Once this laser line generator is making proper use of output power and optic lens fan angle, after projection of different line lengths of 0.5 meter to 6 meters, it provides users excellent line positioning results for laser cutting, laser car wheel alignment, laser medical therapy, military targeting and lab experiment work etc. 
On condition that uniform 635nm red line laser module applies an AC/DC adapter, without spending extra time on alkaline battery power source, it is able to work with constant red laser beam emission from a 650nm red laser diode within 5mW to 100mW. It makes long distance extending line aligning results for close distance, long distance and formal lighting working occasion etc. When laser line generator makes constant line alignment within 10 hours per day, it achieves high level of laser light cycling use, and long lasting line indication for all machinery processing works, including laser cutting, saw mill, textile garment processing, lab experiment and high tech etc. 
With the assistance of a laser alignment mounting bracket, together with electric wires extension for both of uniform 650nm red line laser module and DC power supply, it always allows easy reaching and no barrier line indication for a lot of application fields. Whenever it makes freely adjusted laser beam focus and laser line emitting direction, within the longest work distance of 25 meters and other formal lighting working occasion, it brings users quite nice line generation as expected. For the most important of all, according to high attention to any potential thermal energy hurt to human eyes and correct wearing of lase safety goggles, this industrial alignment laser just makes easy and fine line measurement for all working occasions effectively.
