You can even dial it in to be larger or smaller. Just thought I'd share the effort. You can buy the expanders from
www.meshtel.com for $50.00. I glued it to the colimator adjustment ring. PS works for dpss lasers as well.
suppose you're thinkin' about a plate o' shrimp. Suddenly someone'll say, like, plate, or shrimp, or plate o' shrimp out of the blue, no explanation. No point in lookin' for one, either. It's all part of a cosmic unconciousness.
