The work of red dot laser alignment is not the same as a red laser pointer. Anyway, this laser dot measuring tool is not being used for presentation work, but mainly workable for continuous dot positioning in various work surfaces, such as steel board, garments, wooden board etc. it is required to make long term continuous dot positioning in practical use. It is o kidding to design its electrical power source.
In order to get continuous dot positioning on various working surfaces, red dot laser alignment just selects DC input power supply. When it is getting wide output power range from 5mw to 100mw, this laser diode module is just adopting the high operating voltage of 4.2v DC input power supply so as to always keep its bright and visible enough alignment laser dot emitting source efficiently. The operation of this red laser module is allowing free select of output power in basis of work distance, height and surrounding working environments.
The practical dot aligning from red dot laser alignment would've aped in those of quite harsh work environments. For instance, higher operating temperature up to 45 degree celiac, it is still able to keep reliable alignment laser dot projection, not be affected by real working environments. At the same time, red laser dot aligning is also able to bear super lower temperatures lower of only -10 degree celiac. This red laser alignment employs high duration structure in type of aluminum alloy housing material, which has just made this laser diode module workable under quite wide range temperature.
It is not a hard work to operate this professional dot measuring tool of pro red dot laser alignment. However, its operation should always pay high attention to powerful laser light radiation and reflection in continuous dot aligning work. Users should just remember to select a pair of laser safety goggles to get secured alignment laser dot projection sadly.
