Whenever line measuring work is processing at different work distances, it might be far more enough than formal hand reaching. After constant technical innovation of advanced 650nm red laser diode tech and a qualified optic lens with wide fan angles, it is developing a quite practically used device of a 650nm red line laser module. It is working well with high density and formal brightness red laser light source emission directly from a laser diode. Cooperating with external electric power source, only after its proper mounting onto those of machine or device, this laser line generator just brings users quite satisfied line positioning results for all application fields.
The usual line alignment is not the same as any other manual line drawing or printing work at all. This 650nm red line laser module is applying an import 650nm red laser diode within 5mW to 100mW as beam emitting source. The basic use of 5V, 9V 1000mA DC power supply has just supported long lasting and constant red laser beam emission at several miles far away. In addition, in practical precise line positioning work, this laser line generator is not simply used for close distance and inner room, but also providing users excellent line positioning result for laser cutting, saw mill, lumber machine, textile garment processing and lab experiment work etc. 
Being made with a qualified glass coated lens within wide fan angles of 10 to 110 degree, unlike the use of any prior line drawing work, the real use of a 650nm red line laser module should only be selected with correct output power and optic lens fan angle. It emits high density red laser light source at long extending distance, but also provides users high linear quality and highly straight red reference line projection within 0.5 meter to 6 meters line lengths. When this laser line generator is operating within the maximum work distance of 25 meters, it just brings users quite satisfied line positioning result as expected. 
According to the special use of adjustable focus optic lens design, any time this 650nm red line laser module gets proper mounting onto any other machine or device, after its easy screw of beam aperture, it just gets high concentration red laser light source emission at long extending distance. Whenever it is mounting properly onto any other machine or device, after high attention to thermal energy hurt to human eyes and proper wearing of laser safety goggles, this industrial stabilized alignment laser just brings users easy and secured line indication in long lasting use effectively.
