    ... oookay ... so it was only my impatience

    I had two vimeo-accounts too, but one was closed for "too much like a pro!" -- they told me: either fee, or "kill" ... so I've changed to yt again

    The HR is coated for 400-700 nm High Reflect and is a ion plated, super-polished optic. They select the lines using the OC optic , and you have the Kill Green OC. Adding the green line messes with the biological end use application. There are all lines OCs out there for the 643, the other issue becomes the 530.9 line competing with 568. 647 and 568 can strongly fight each other for power, that is why you see some really odd twists with slight detuning of the optics.

    On a good day you might see a few flashes of 575 nm yellow as you tune the optics.

    Watch out for the incredibly fragile glass gas ballast inside the head, and its even more fragile flex connector.
