;D
Ok... so far my testing has combined a bunch of 'patience' (
) and a lot of monitoring DMM's and recording data...
I have made a complete test of the SenKat GB diodes and have compiled a table of the output just as Mike did, but I did it for my comparison chart, all the data will be supplied numerically and graphically. The 200mW diodes... (I'm now laughing) ARE AMAZING! The preliminary power graph goes up to 340mA and the output at that point is around 200mW!!
Steady!! And the diode doesn't get all that hot either.
I haven't pushed it much more than that and I'm seeing some very impressive results so far. My TEC setup is getting a nice rework, which is holding me back from moving any further for the next couple of hours at the least. The data is very beautiful though
Also... just to let everyone know... the conversion between these and the SenKat GB diodes in terms of Thermal/Optical measurement has proven the following: (First thanx Mike, because now my Thermal sensor is calibrated and is working flawlessly!
)
The conversion rate between IR-Free green on the LPM to the thermal meter is (output was steady as a rock! and this is the average of 10 runs which were all within .01 of each other using 4 different laser pointers
)
2.98246
The conversion rate between the SenKat GB diodes on the LPM to the thermal meter is (same as above... tested with 3 pointers of which only one was counted, which was my MXDL project, as all the others were unstable AT ALL... testing also included my home-made labby which was stable on the LPM for a solid 2 minutes!! Not a single reading was different across the entire 2 minute run!!
And you thought this 'Daedal's regulated PSU was a bunch of salami
)
2.95417
The conversion rate for the 200mW diodes (which was the same as the 200mW laser pointer) was
3.05974
Now you're probably wondering what the hell is all this?!?! :-? The reason I wanted to test this is to show that the difference between the thermal reading and the optical reading of the wavelengths (probably the difference was because one was 660nm, and the other was 658nm) is very minimal and can be easily eliminated as a factor in the measurement. As most of you know, the thermal reading is always rather slow and tends to take a couple seconds to update... even though this amazing little thing I made here... yes... it's home-made
... updates quite fast and can sense as low as a milliwatt or less of change! ;D Regardless... The data will all be plotted and graphed and tabulated and supplied for the pleasure of everyone interested.
I also pushed one SenKat GB diode up to 400mA and kept it there without TEC cooling (since the rig is under construction again) for about a minute or so and the output was a steady 197.5mW. Now this is the same diode I pushed to 600mA and is still alive and kicking, so the value could be at the end of life cycle, or maybe at the edge of reasonable results. I didn't go further because I didn't wanted this diode to fry ;D
I hope this gives you all a little insight into what I'm working on right now, and what's more to come. Please bare with me while I get the rest of the setup worked out and finished. Pictures, and much more important stuff will follow very soon
Thanx;
