Under operation with highly clear and accurate dot alignment for all night version fields, it is the most efficient job with a long wavelength made device of 980nm infrared laser diode module. It is operating easy and conveniently as an accessory part. Only after proper use of night version device and easy use of 5V, 9V 1000mA DC power supply, it generates high intensity and high power IR laser light, and converts into highly clear and accurate infrared dot alignment in long lasting use.
This infrared laser diode module applies qualified glass coated lens. In order to avoid laser light decay, it gives up the use of formal plastic coated lens and gets up to 24 hours aging preventing tests. Only if it makes long lasting infrared dot projection within 8 to 10 hours, after correct use of output power and freely adjusted laser beam focus, it gets concentrated infrared laser light and efficient conversion of the clearest IR dot alignment in all night version fields.
