If there is not a good idea for users to make super accurate cross line immediately, nothing would be much more effective than the use of Berlinlasers green cross laser alignment. It is using high quality glass coated lens with different optic lens degree of 10, 15 and 110 degree, which is easily obtaining highly accurate 90 degrees two perpendicular green laser lines on various working surfaces. Owing to its good use of 532nm green DPSS laser tech, unless its use under sunlight, users are only need to make free choice of output power and optic lens degree, green laser alignment gets accurate cross line measurement precisely and accurately.
This green cross laser alignment gets the best use of qualified metal heat sink cooling system and APC driving circuit board, it is just keeping extremely stable cross line source generation in long term use. It is workable within long term use. However, this green laser module is only accepting operation within 8 to 10 hours a day, and then cooling down. It will make great work to reduce laser diode and electric driving circuit board burning out or damage. Users can install this green laser alignment on different machine or device, getting ideal measurement for all industrial and high tech work fields effectively.
