Once users are trying to make super accurate cross line targeting on those of hard reaching working places, it is the best chance for users to make good use of a Berlinlasers green cross laser alignment. it is keeping bright and visible two perpendicular lines with accurate 90 degrees. According to easy choice of optic lens degree of 10, 15 and 110 degree, this glass coated lens made green laser module makes quite convenient and easy cross line generation on all targeting surfaces effectively.
This green cross laser alignment is very easy to operate. After easy connect with 3V or 4.2V DC input power supply, it begins to work with constant and highly straight green cross line source generation from laser beam aperture immediately. This green laser module is not adjustable focus. However, front part of laser beam aperture is still able to adjusted freely, and then making sure of high accuracy cross line source generation with quite satisfied line thickness. This advanced cross line laser module is making great work for laser alignment for screen printing system, military targeting, laser medical treatment device etc.
