Thanks! - looking forward to the exchange - ie: this post - LOL - glad to ignite such a volley!! I will be replying in kind / clarifying shortly...
RE: Optics, not entirely sure whos, as they are hard-sealed, but definitely multiline - yes, the pic IS dark, but this Argon produces all Ar lines - definitely a nice, rich 457 and up to 528 lime...of course strongest @ 488, which we are measuring when stating 'power output' of 1W+...also, the raw beam is 1mm and divergence is really, really tight - don't have specs, but I'd guess (have not had time to measure) 1.2 mRad or less...see replies below for more info... - thanks!
