Hey,
Not sure if this is the exact forum to ask, but for my project, I wanted to create a laser array. The power doesn't necessarily need to be strong, nor does the wavelength need to be considerably the same, just visibly strong enough to see when you put your hand through. This would potentially be powered by an Arduino.
It would look something like the image attached.
My question is: Is there any place where I can buy such a laser array like this, where each laser is closely next to another? I'll consider modifying my design based on what is available, not sure exactly where to look.
No sensing necessary.
