I have access to a small CNC but it's not capable of milling glass. Can I get away with perspex? It doesn't have flood coolant or a high speed output so the best I can mill on it is perspex with a good cutter. I just haven't got enough experience in designing lenses to know if this machine is...

Projected onto dirt, concrete, grass, metals, (that's part of the experiment really), Budget is tight at under 1k. Space isn't too much a of a problem but strength is, it is to be mounted on a moving platform. 980nm at this point because it is significantly safer given the time and dose since it...

No worries, anytime.

It servers as an active sensor for a robot. Some monitoring equipment looks for the line and measures the distance to it. The accuracy and precision depends on many factors, but the thickness of the line is extremely important because the sensing equipment can measure down to micro meters but if...

Hi all, I'm new here so forgive me if I haven't been able to find the answer, but I'm chasing a lens to focus a 980nm diode down to the smallest spot I can at around 50m. I'm looking to make a low angle scanner for about 50m distance with a very small spots size for drawing thin lines at a...

I scoured the net looking for the best line generators and the truth is, if you can manage with a single line instead of a cross, Powell Lenses. Best around but not cheap. If you want cheap, the diffractive ones are. They will be brighter in the center due to the way they work. If you want...
