The desired beam from green cross laser alignment is much more complex than formal dot or line laser device. When glass coated lens is available with different lens degree of 10, 15 and 110 degree, it is just generating different dimension cross line source in distance. According to different selection of optic lens degree, this 532nm green laser module is just getting different cross line length from 0.5 meter to 6 meters. The real cross line generation is getting designed best work distance at 3 meters. However, this green laser module is always keeping quite low laser beam divergence, thus the real cross line generation is always allowing the operation with maximum work distance of 25 meters.
This green cross laser alignment is not used for quite close distance, but also workable at quite longer distance once it is getting the use of quite high power up 50mW to 100mW. In order to assure accurate enough cross line alignment result, it should be used without sunlight. At the same time, high power green laser module is also adopting even larger size tube diameter of 26mm. Together with its external electric power source, there is always enough space reserving as its metal heat sink cooling system, and finally assuring stable and reliable enough cross line alignment in long term use.
No matter what kind of working surface, the use of green cross laser alignment is always used with the assistance of a laser alignment mounting bracket, and then making sure of no barrier operation on all targeting surfaces. Noncontact green cross line source is able to be adjusted within three dimensions, and then achieving any hard reaching places and harsh working occasions. Whenever users are remembering to wear proper 532nm wavelength preventing laser safety glasses and avoid eye exposure to powerful laser light, a high power green laser module is still getting no danger use effectively.
