If users are not able to getting clear and accurate dot measurement at different targeting surfaces, not easy to reach with a simple red laser pointer or other formal manual dot projecting tool, it is just making super nice dot measurement after the use of a pro red dot laser alignment. It is being made with the purest red laser light emitting part of 635nm red laser diode. When it gets the lowest laser beam divergence and makes the best use of cooling system inside highly durable metal housing tube, this compact size tube made 635nm red laser module achieves excellent thermal emitting, and increasing stability red reference dot projection onto various working surfaces effectively.  Different from a formally used 635nm red laser pointer, the genuine use of pro red dot laser alignment should have to work for quite long time and maintain good laser beam stability in continuous use. It is generating the lowest laser beam divergence of less than 1mard. Even though it is pointing at close distance of 10cm, it just gets as small as 0.3mm dot diameter, which is also getting as small as 1mm to 2mm at 2 meters work distance. For the most important of all, owing to its easy screw of adjustable focus optic lens, 635nm red laser module enables high speed red laser light concentration, and the most accurate red reference dot projection as long as 25 meters. In any type of clear and accurate dot measurement onto various working surfaces, pro red dot laser alignment makes the best use of qualified glass coated lens. It is performing with high transmittance red laser light emission from beam aperture. In addition, after quite strict laser beam stability tests up to 24 hours and quite special use of glass window in front of laser beam aperture, this 635nm red laser diode module is always performing with high quality red laser light emission. There is also no laser light decay or blur in any type of special working occasion, such as moisture or dust etc. Any time pro red dot laser alignment is operating as an accessory part, with the assistance of laser alignment mounting bracket, it makes no barrier and no mistake red dot projection onto any raw material surface. Noncontact red alignment laser dot with correct use of output power makes no mistake dot measurement for multiple application fields, including laser marking, laser engraving, military targeting and other high tech work fields etc. In any type of clear dot measurement with high power red laser module, it is just a key issue to wear correct laser safety goggles and avoiding eye exposure until achieving highly secured and quick dot measurement constantly.
