So, we should adjust the alignment until the red shifted (not quite perfect) laser light becomes a (perfect) blue shifted laser light? My lens coating is more gold colored than green. Will that make a difference?

I have Zebra label printers that print 4" X 6" shipping labels. They're 203 DPI thermal printers. I could print peel and stick thermal targets that turn black wherever a low power laser contacts the thermal label.
Apparently, I didn't build that! :-)
