Today’s module is quite special, it is not the common dot-line-cross module we see. Its pattern is a perfect circle with a center point. The head of the laser module can be rotated to adjust the focal length and change the thickness of the laser light. The built-in special lens makes the laser light appear in a circular shape. The power supply has an adjustment knob, which can adjust the voltage to change the laser output power and the brightness of the laser.
We can customize the circular laser of red/green/blue light. The divergence angle used here is 56°, and there is an option of 34°. There is a dot in the center here, or you can customize the center without a dot.
