DC Power Supply 980nm APC Driving Circuit Device of Infrared Laser Diode Modules
This 980nm infrared laser diode module applies an external AC/DC adapter, accepting wide range electric current of 100V to 240V, it is applying for various working environments, but also assuring continuous infrared laser beam and infrared reference dot projection in continuous use. It is allowing easy installation onto those of night version device. Only if it makes correct use of output power and proper adjustment of both beam focus and IR dot projecting direction, this infrared dot laser always makes no mistake IR dot measurement at various work distances effectively.
