When I am trying to look for a quite efficient and quick cross line measuring method, it is just not a clever idea for me to still make use of simple cross line drawing from a triangular meter or blocking board, on contrary, I just get the selection of economy red cross laser alignment. On basis of its primary use of import 650nm red laser diode, equipped with different optic lens degree made glass coated lens, this cross line laser module is always effective enough to get quite complex two perpendicular red lines with accurate 90 degrees on different working surfaces.
It is always an easy job for users to make use of economy red cross laser alignment. It is using continuous electric power source from DC input power supply, which is an external equipped electric power source. Besides its ability of long term continuous electric current supply, this cross line laser module also gets enough space reserving as its cooling system. According to its employment of metal heat sink cooling system, although this cross line laser device is getting quite compact size structure, however, it has been enough for users to get highly reliable and stable cross line targeting in use.
On basis of the employment of DC power source, when this economy red cross laser alignment gets wide range output power of 5mW to 100mW, it is just workable for all distance and all types of continuous cross line targeting works. There is always no appearance of laser light becoming dim or decay only if this cross line laser module is being equipped with proper operating voltage electric power source. At the same time, according to the selection of different output power, this laser device is just adopting 3V or 4.2V DC power supply.
In some long distance cross line targeting work, such as military targeting, laser medical treatment device, and large scale laser car wheel alignment outside, economy red cross laser alignment would be selected with quite higher output power up 50mW to 100mW. Only if it is being used with quite higher operating voltage of 4.2V DC input power supply, this red cross line laser can finally get bright enough cross line source generation all the time. At the same time, it is also a necessity for users to pay attention to powerful red laser light and laser reflection, according to prospering wearing of laser safety goggles, this alignment laser can easily achieve high security and wonderful cross line measurement effectively.
