Easy Operating 980nm Infrared Line Laser Alignment- Unless the use of any manual line drawing or printing work, in order to make easy and quick line measurement under night version fields, it is operating easy and quick with a long wavelength made Berlinlasers 980nm infrared line laser alignment. It projects invisible and intense infrared laser light directly from a 980nm infrared laser diode. Cooperating with night version device and 5V 9V 1000mA DC power supply, it keeps work with highly intense IR laser light emission, and highly clear and accurate infrared line projection at various work distances. This 980nm infrared line laser module is working well with highly straight and fine infrared line emission from a qualified glass coated lens or separate crystal lens. It passes through up to 24 hours aging preventing tests and allows operation by skilled users or professionals. When it makes freely adjusted laser beam focus and IR line emitting direction, within freely installed distance of 3 meters, it assures no barrier, low price and long lasting IR line generation for military targeting, intelligence system, laser medical therapy device, and high tech work etc.
