Without any prior line drawing or line printing works, it is the most easily job to get high accuracy measuring result with the assistance of a high precision alignment laser. Laser tech engineers are designing laser modules with 405nm, 445nm, 515nm, 532nm, 635nm, 650nm, 808nm and 980nm, and different output powers. After easy connect with an external DC input power supply, it is making an easy, non contact and fast response dot, line, cross line, and parallel line alignment results efficiently.
