GB: PL520 murder fund






The only time i used one was to engrave my safety glasses at school when the teacher wasn't looking :D I haven't bought one because there isn't anything i can do with a dremel that i cant do with some other tool i already have.
 
I love my dremel. Its great for small things and its great since I don't have the money(yet) for much larger tools.
 
I've got the diode and I am collecting all the data and putting it into graphs (yeesh it's a lot to write down) It will probably take me until Saturday to collect and compile all the data into graphs.

The wavelengths are 516.5nm and 518.75nm both at room temp.

Can't wait for the further testing!

I'd be interested in beamshots of the 516. I am set on the idea that I have a 523+ although I might just have to get it metered or do it myself once I snag one...Either way, I plan to get another later on down the road.

Working on it :D

This good enough for now? :p

Nice. How do you know the exact wavelength? Is it like peregrine where you have the crosshair thing?
 
So you just estimate the decimal places then based on the graph? I guess thats good enough for what we need though.
 
Yeah, my spectrometer reads within +/-.5nm so I zoom in on the graph and round to the nearest .25nm.

The lights will be off for the spectrometer readings :)

Less than 520nm. That looks good. Does it shift downwards when the current is push up ?
We want the current/wavelength chart. :)

I will second this post in its entirety.

If the wavelength shifts downward with more current/heat I will be tempted to run mine a little closer to its max peak.
 
Wow! It always looks nice when there's lots of instruments around.
Btw, would the wavelength measurements change if you used a white piece of paper instead of reading the light reflected off the OPHIR?
Looks good that it's below 520. That way the difference would be more pronounced!

So far it looks like increasing the current increases the heat, which increases the wavelength.

The only time a surface would affect the wavelengths readings is if the floureses. I have tested it with a non-flouresent material and I got the same wavelength ratings. :)
