Under operation of high precision and high accuracy dot alignment of those of night version fields, it makes efficient job with a 1470nm infrared laser diode module. It projects invisible and highly intense infrared laser light from a 1470nm infrared laser diode. Being made with qualified glass coated lens and glass window, it is generating high intensity IR laser light and highly clear infrared dot in distance. Only after its freely adjusted laser beam focus and infrared dot projecting direction, after freely adjusted laser beam focus, this infrared dot laser gets concentrated IR laser light and high precision infrared dot alignment for measurement, laser communication, spectrum analysis and scientific research work etc.
