So my day started pretty hectic...
Started with a Jiu Jitsu/Judo tournament (got guillotined in the semi-finals). Then a rugby match, then a barbecue. Where I proceeded to eat many pounds of juicy dead animal.
After that...there's THIS! You know, just trying to meter the wavelength of the ~609 line. Looks to be the Neon line at 609.6. Though it's very hard to tell... Will have to reattack this issue again tonight, or tomorrow.
What do YOUR current workspaces look like?
Enjoy the juicy pic
(Dr. Sam really owes me a drink for this)
Basically, you tune a micrometer on the side of the Verity, that turns a reflecting diffraction grating through a set of mirrors, to another slit in the back. So the light comes in one slit, the grating splits it up to its place in the spectrum, and it hit the back slit, and hits a photodiode that says "yes light" or "no light".
Now when there is light, the meter will start pinging depending on the power to the PCM. The more power, the more sensitive.
In this case, the 612nm light would still be telling the meter to go up, even down by the 609-609.6 range. So I had to get the measurements of how high at 607.5nm, and 608nm. I took measurements for when there was, and was not a ~609nm line present. Hence the grating to move in and out to check for the line. The difference between those two figures at 608nm was double, to even 2.5 times the difference at 607.5nm. It also reads 1.5nm low. So that puts this line right around 609.5nm. the Neon spectral line in question is 609.6nm. I think we nailed it
