Hello all,
Im a newby to the laser world and recently built a 3 watt 445nm setup. I have a g2 lense and noticed that the beam goes from a pinpoint to a rectangular shape as distance increases. Is there a way to keep the beam at a pinpoint regardless of distance? I am willing to purchase additional lenses if necessary. My goal is to use up to 250 1x1 inch mirror tiles to reflect the beam and create a "laser beam door."
