Although he'd be better of with three element lens if he's gonna use it for pointing. People pretend g2 lenses are great when in reality they have terrible divergence without a beam expander, but they're good for power.The NDG7475 would be my choice as well. It has a can with a window and no lens attached to the can, so you can use a G-2 lens.
The 2 element works wonders no splash and less power loss!
Sounds nice. Were do I get a 2 element ?
