Adjustable Focus 445nm Blue Laser Diode Modules
What is an easy job to make highly clear dot alignment at quite long work distance? It is not easy to reach with a simple blue laser pointer. Instead of spending extra time on alkaline battery power source, only after proper use of 5V, 9V 1000mA DC power supply, this blue laser diode module is working well with high intensity blue laser light emission from beam aperture.
On basis of the use of 16mm diameter anodized aluminum alloy housing tube, under operation of mechanical moving or shocking and other wide range operating temperature, this blue laser diode module is working well with highly clear and accurate blue dot alignment at great distance of 25 meters. Only after its correct use of output power and freely adjusted laser beam focus, it assures increasing accuracy and brightness dot alignment for great distance and long lasting work perfectly.
