Re: PERMANENT THREAD: Ebay& other internet FINDS of interest- read all the OP please
Not much demand/higher complexity.
The Coherent Compass range is expensive to begin with, being such high quality. SLM, long coherence length, arguably the best beam specs I've ever seen (spec is 0.32mm at aperture). M2 factor is probably as close to 1 as you'll ever see, at least in anything that size. But a 561? That's probably a custom job, thus way more expensive than your regular 532nm Compass. Not to mention that one is tested so that immediately bumps up the asking price.
Edit: That may have been a rhetorical question?
More interesting items for us all. Good find Diachi.
Why do 561's have to be so expensive.
