HI, jeff

On this page : http://www.beamtech-laser.com/en/proInfo.aspx?m=20101216100729203892&n=20101222115304745038&protype=20101216101714765927

they speak of that kind of laser spot resolution.

But only by the looks of it I think its going to be a $$$$$$ digit number ...LOL

The Bungard drum plotter has laser spot size of 0.005mm/0.0002inches.  This is a resolution of 5,000 dpi.  The laser inside is a red 670nm laser.  How do they achieve this?  What laser and lenses are used?


Is red sensitized photoresist film common?  Where can it be purchased?
