It gets at least 3 times brighter red laser light than formal 650nm red laser, after quite low laser beam divergence of less than 1mrad and special Tem00 laser beam mode, this laser line generator always gets ultra high fineness and high brightness red line projection at long extending distance.

In those of industrial and high tech precise line positioning work fields, after correct use of output power and optic lens fan angle, this 635nm red line laser module always makes sure of quite easy reaching, no barrier and no mistake red line indication onto any vertical or horizontal surface. When it gets proper adjustment of laser beam focus part, after its immediate red laser light source concentration, this alignment laser enables increasing accuracy and brightness red line alignment at even longer distance. When users are aware of any powerful red laser radiation and potential thermal energy hurt to eyes, after proper wearing of laser safety goggles, it still brings users quite easy and secured use for all line alignment fields.

In those of industrial and high tech precise machinery processing work fields, even though users are not able to make ultra clear line indication with those of manual or mechanical line aligning tool, it should be a much better job for users to operate a highly intense beam emitting tool of a 650nm red laser line generator. It is working well with intense and visible red laser beam emission from an import 650nm red laser diode. Cooperating with a qualified glass coated lens within wide fan angles and strict laser beam stability test before its flowing into laser market, this 650nm red laser module just brings users quite satisfied line positioning results for all work fields constantly. 
Usually 650nm red laser line generator applies an import 650nm red laser diode as its beam emitting source. It gets less brightness red laser light than 635nm red laser. However, when it gets the longest developing history and quite mature laser diode tech, the finished product of this laser device is not only getting quite low production cost, but also maintaining ultra stable and reliable red line indication for long lasting use. As a result, after its cooperation of a metal heat sink cooling system inside a durable anodized aluminum alloy housing tube, this red line laser just gets excellent thermal emitting and ultra stable red line alignment within long lasting work time of 10 hours per day.
According to the adoption of 5V, 9V 1000mA AC/DC adapter, not any longer spending extra time on battery change, this 650nm red laser line generator always makes continuous red laser beam and red line alignment for a lot of raw material processing works. Further more, after the use of a qualified glass coated lens within wide fan angles of 10 to 110 degree, after projection of highly fine red reference line within 0.5 meter to 6 meters lengths, this 650nm red laser module is making quite satisfied line positioning results for laser cutting, saw mill, lumber machine, textile garment processing, laser medical therapy and high tech work etc.
After the use of a laser alignment mounting bracket and special designed electric wires extension, this 650nm red laser line generator always makes quite easy installation and quick reaching of red line generation onto any vertical or horizontal surface. The unique use of adjustable focus optic lens enables quite immediate red laser light source concentration, and highly efficient conversion of ultra clear and bright red line alignment at longer distance. When red alignment laser is operating with high power up to 50mW to 100mW, it is a key issue to pay high attention to thermal energy hurt to eyes. Only after proper wearing of laser safety goggles and avoiding eye exposure to laser beam aperture, it just brings users quite satisfied line positioning results for all machinery processing works effectively.
