515nm Green Line Laser Alignment In Measurement and Construction Field Based on the use of a 515nm green line laser alignment, after easy connects with 5V, 9V 1000mA DC power supply, it makes constant and highly intense forest green laser beam emission directly from an import 515nm green laser diode within 5mW to 100mW. It is designed with cooling system and ultra compact size tube design, which is easy to carry, and making long time lasting green line projection onto all working surfaces conveniently. Basically 515nm green alignment laser applies a qualified optic lens within 10 to 110 degree fan angle and adjustable focus optic lens. It enables high transmittance green laser light emission, increasing accuracy and fineness green line projection at longer distance and higher lighting occasion. When it gets correct use of output power and optic lens fan angle, it enables perfect use for measurement and construction fields effectively. Construction field application In construction, green laser line is used to determine the vertical direction of the building, such as the verticality of the wall, the vertical installation of the elevator shaft to ensure the structural stability and safety of the building. With the help of measuring instruments, the distance, height and angle between objects can be measured by using information such as the length and angle of the green laser line, providing accurate measurement data for construction, road construction, etc. https://www.berlinlasers.com/515nm-forest-green-line-laser-alignment
