Why don't you post something in the welcome section so we know who you are.
It's tax day here too...no worries!
hey dave whats the beam size of the 635 and 655 labbies?
thanks
These are old skool with square beams
Quick and dirty measurements (I'm making dinner )
635nm = 4x5mm @ aperture
660nm = 4x6mm @ aperture
635nm = 15x15 @ 20 feet
660nm = 15x16 @ 20 feet
That should put them both ~1.7 mRad
Peace,
dave
