|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.
