In order to make sure of high accuracy dot measuring result on different working surfaces, green dot laser alignment is always getting super low laser beam divergence of no more than 1mard. Even though green reference dot is pointed at about 2 meters work distance, it is still able to keep small size dot diameter of only 1mm to 2mm. At quite close distance of 10cm, green laser dot is only available as small as 0.3mm. Once users are trying to make dot measuring work in distance, in order to assure its precise enough dot measuring result, it is always accepting the maximum work distance at 25 meters.
This green dot laser alignment is a very nice and professional dot measuring tool. When it is keeping constant green reference dot targeting from laser beam aperture part, it is just workable for quite long term measuring work. Instead of simple dot positioning or burning experiment use, this green laser module is just greatly applied for those of industrial machinery processing and other high tech dot aligning work fields etc. It is also able to work with high stability green reference dot targeting for laser marking machine, laser engraving machine, drilling system and others etc. In quite harsh working occasion, such as strong interference or strong static, it is not affected, but just supporting continuous green reference dot targeting within 8 to 10 hours a day.
In some of special working place where human hands or other mechanical dot alignment tool cannot reach easily, noncontact green reference dot from green dot laser alignment is just easily reaching any working surface, and then achieving high accuracy dot instruction easily. Whenever users are paying high attention to powerful green laser light with a high power green laser module device, only according to proper wearing of a pair of laser safety glasses, this alignment laser gets no danger and clear dot measurement easily.
