Unless the use of any visible laser devices, the genuine use of a long wavelength 980nm infrared laser diode module has just assured quite stable and clear infrared laser light source emission and IR dot indication in all night version fields. After connects with 5V, 9V 1000mA DC power supply, during the transmission of infrared laser light source, it gets no disturb by external light, and keeps work with stable work in various complex working environments. 
In practical precise IR dot indication and measurement works, IR laser diode module gets ultra compact size and durable metal housing tube design, which enables easy integration and installation onto other night version device or equipment properly. After quite strict process manufacturing and quality inspection, it enables ultra stable and reliable IR laser dot projection and long time continuous work. Only after its correct use of output power and freely adjusted laser beam focus part, it achieves high precision and high brightness IR dot alignment for all night version fields.
Applications: infrared laser welding and material heating, scientific experiment, biomedical, optical research
