Hi
I have a 150mW 405nm Blu-ray Blue-Violet Laser diode and I would like to burn things at several meters (2-3 meters). The laser was sold housed in an aixiz module with adjustable lens (don't know the details of the lens).
With some calibration, I could find the distance of the target to burn so I could automate the focus on the target.
Searching on the website, I saw I would need a beam expander to focus at long distance (I got a brunton http://laserpointerforums.com/f49/super-cheap-beam-expander-86604.html to make some tries) but I don't know what is the best to put after it ? a moving convergent lens ? if yes where could I found such lens please ?
Thanks for any advice
