Under operation of highly clear and accurate dot measurement for all kinds of night version illumination work fields, it is far more enough to reach with any visible laser device or manual dot projecting tool. It is not the end for laser users to develop a much more practically used device, such as a 980nm infrared laser diode module. Under operation with its proper mounting onto any night version device and external electric power source supply, without any serious relying on any manual labor force input, this infrared dot laser alignment just assures the lowest price and the most reliable infrared dot generation under all night version illumination fields effectively.
Comparing with a simple infrared laser pointer only used for temporary dot positioning work, not any longer in need to make alkaline battery change, this 980nm infrared laser diode module is just able to work with constant infrared laser beam and infrared reference dot projection from beam aperture. Every time it gets constant power source supply from a 5V, 9V 1000mA AC/DC adapter, after leaving even larger space for tube cooling down, this infrared dot laser alignment just keeps work within wide range output power of 100mW to 500mW.
In occasion that infrared laser diode module is projecting highly intense and powerful infrared laser light emission from laser beam aperture, besides its operation for close distance IR dot projection within 50mW, it is applying for long distance and high precision IR dot projection within long work distance of 100 to 1000 meters after the use of high power IR laser up to 300mW to 500mW. For the most important of all, owing to special use of adjustable focus optic lens, this infrared dot laser alignment just gets highly concentrated infrared laser light, increasing accuracy IR dot projection for a lot of application fields, including military targeting, laser medical therapy, intelligence system, infrared laser sight, high tech and lab experiment work etc.
Being made with APC, ACC driving circuit board, whatever output power it is selecting, 980nm infrared laser diode module is just keeping work with constant output power and electric current supply, and no effect by overheating and over current impact as well. It just allows long lasting infrared alignment laser dot projection within 8 to 10 hours, and long operating lifetime of more than 8,000 hours.
