Not easy to get ideal dot aligning work under night version fields, it always makes good job with a long wavelength made device, such as a 980nm infrared laser diode module. It projects high intensity infrared laser light. Only after proper use of night version device and easy use of 5V, 9V 1000mA DC power supply, it assures highly efficient conversion of clear and accurate infrared dot alignment at various work distances.
After special use of qualified glass coated lens and glass window in front of laser beam aperture, owing to its strict laser beam stability and aging preventing test up to 24 hours, this 980nm infrared laser diode module is working well with good laser beam stability and no decay light infrared dot alignment as long as 100 to 1000 meters. Within freely installed distance of 3 meters, it brings users no barrier dot alignment for night hunting, infrared laser sight, military targeting, laser medical therapy device etc.
