When line aligning work is processing under all kinds of night version fields, it would make good job after the use of a long wavelength made device of 980nm infrared laser line generator. It is performing with invisible infrared laser beam and IR reference line from an inner 980nm infrared laser diode. In occasion that it makes advanced use of separate crystal lens with different fan angles and good cooling system, whatever kind of working surface it is pointing, this compact size tube made
