Aixiz module finally arrived!
After waiting for a month, I finally got the module from Aixiz. I had been very busy anyway, so the delay didn't really matter. Here it is: the 650nm 5mW Aixiz module! I also got an extra lens for it, made of glass. I'm sure it's better suited for a laser CNC than the plastic one the module came with. This module is needed for collimation and heat sinking. I will put the laser diode inside the module and focus the beam with the glass lens. Next up: how to insert the 250mW laser diode into the Aixiz module.
