In any special work fields of clear and accurate dot alignment for those of night version application fields, it is a good job to apply a long wavelength device, such as a Berlinlasers 980nm infrared laser diode module. It is projecting the most powerful infrared laser light from a 980nm infrared laser diode within 100mW to 500mW.
In occasion that it is working well with night version device and 5V, 9V 1000mA DC power supply, available within freely installed distance of 3 meters, this 980nm infrared laser diode module always makes easy reaching, and good direction infrared dot alignment. Every time it makes correct use of output power and freely adjusted laser beam focus, not workable at all by manual labor force input, it assures low price, high stability and long lasting IR dot alignment for night version infrared laser sight, military targeting, intelligence system, surveillance and monitoring system etc.
