On consideration of low price and high stability line projection at various work distances, and other formal lighting working occasions, it is making good job to operate a Berlinlasers economy red line laser alignment. It projects intense red laser beam directly from a 650nm red laser diode. Owing to special use of thermal emitting and APC, ACC driving circuit board, configured with 16mm and 26mm diameter tube, it enables easy installation, and quick reaching of red line emission onto any raw material surface.
Only after easy connects with 5V, 9V 1000mA AC/DC adapter, not relying on any manual labor force input, this 650nm red line laser module keeps work with long lasting red line emission within 8 to 10 hours. It gets no effect by increasing temperature and serious electric current impact as well. After correct use of output power and optic lens fan angle, it just assures no mistake line measurement for laser cutting, lumber machine, sand milling, textile garment processing and high tech work etc.
