No matter what kind of working surface it is pointing, in order to make clear enough dot measurement under those of night version fields, it is always making good job after the use of a long wavelength made device, such as a 980nm infrared laser diode module. It is projecting intense IR laser light directly from an inner 980nm infrared laser diode within 100mW to 500mW. On condition that infrared dot laser is operating as an accessory part, after its proper use of night version device and gets constant power source, it makes sure of the best quality IR laser light source emission, and highly clear IR dot alignment under all night version fields.
After the use of an import 980nm infrared laser diode, different from a simply used IR laser pointer only used for temporary dot positioning work, this finished product of infrared laser diode module always gets increasing laser beam stability of at least 40%. It is adopting an inner metal heat sink cooling system, which just gets even better thermal emitting than formal air or water cooling. When it is adopting highly durable anodized aluminum alloy housing tube with 16mm and 26mm diameter tube, whatever kind of working surface it is pointing, this infrared dot laser is performing with superior nice thermal conductivity, and highly stable IR dot alignment under any other harsh working occasion of mechanical moving or shocking etc.
In practical IR dot measuring work fields, 980nm infrared laser diode module always makes good job for clear IR dot indication for a lot of application fields, including military targeting, night hunting, laser medical therapy device, and intelligence system etc. It should only be equipping with other night version device, such as a CCD camera, black and white camera or IR laser camera. After proper use of 5V, 9V 1000mA DC power supply, this 980nm infrared dot laser is always working with continuous infrared laser beam emission, and supporting wide range output power of 100mW to 500mW. 
Being made with an important design part of APC, ACC driving circuit board, without any affect by increasing temperature, the genuine use of 980nm infrared laser diode module gets reduced possibility of tube burning out or damage. It assures highly stable and reliable IR dot indication within constant work of 8 to 10 hours per day. When infrared alignment laser makes proper adjustment of both laser beam focus and IR dot projecting direction within three dimensions, after proper wearing of 980nm wavelength preventing laser safety goggles, it makes sure of high security and high fineness IR line alignment constantly.
