No, I mean the electrical power from the PSU to the tube's anode/cathode should be able to go to 100%
when it's cold. Sorry if I was not clear on that.

It does, 100% goes to the tube right off the bat, all 9.48A. That's the max for the PSU, says it right on the sticker :)

However, the current control pot on the PSU hits max (9.48A) at about a quarter turn. That's what's wonky about it.

Bah, well my reading comprehension must be at an all time low. This is the second time this has
happened to me in the last couple days.

Hopefully it is only the pot. Anything more serious than that and it might be best to just leave it as-is. I
am fairly sure the issue involves a resistor of some type.

I jumepered a different pinout on the remote, and now I can get a full pot turn before max current. Much more reasonable :)

Seeing apparatus for aligning laser :p

5 blues :)

I tried.

At low current, I get pure 568nm, about 8mW or so.

It's the camera. The white balance is damn near perfect to the human eye.

Fun fact. The eye isn't picky about white, which is nice in cases like this. It's got an auto white-balance that has a very large swing. A standard 60W bulb is white, but bring it outside during the day, and it will suddenly turned yellow. :tinfoil:

These are all "white":

This may actually be beyond the ability of the camera's white balance adjustment to correct. Cameras
and monitors do not handle very narrow bands of the spectrum in the exact same ways our eyes do.
Also, very intense points of light tend to go towards white.

This is such a cool piece of equipment! Glad to hear you fixed the pot... Btw bloom the junk at the front was probably the etalon. Most white lights come with one to allow wavelength separation/selection. Removing it gives you the white. :beer:

On the lookout for one of these now :p that 568nm is a wicked color!

I don't believe so. There were no optical elements. Just metal pieces, no glass/plastic. It included a second beam stop, and a piece the cut the spot in half permanently. So it was a glorified far field beam corrector of sorts.

Really? That's very interesting bloom. Both of the ones I've seen both had optics in front, one even had a tuning prism in front. I'm surprised

I think these runs are doing something. The other two blues are coming in quicker, and brighter, each time.
