I picked up one of the FieldBest optical power meters on eBay and also have a LaserBee and old Newport 818P-110-19 that's out of calibration. The FieldBest seems to work pretty well. I tried testing 2 532nm lasers I have, a "Laser 301" 532nm laser from eBay and a Alcon laser which is supposed...

I picked up an old Newport 841-P-USB with a 818P-110-19 thermopile head. Newport don't seem to supply software for this unit any more (the legacy software doesn't work). But I can communicate with it over serial. I'm now trying to figure out how out of calibration it is. It was last calibrated...

I've seen a few threads on here discussing lasers with a spot size in the micron range, but I'm still at a bit of a loss as to what I would need to buy/build. Can anyone offer any tips/useful links? I've recently picked up a couple of XY and XYZ stages which claim to have micron resolution...
