OK, both lasers are freshly metered, graphed and packed ready to ship Thurs arvo.
There's a heap of graphs, the excel log files, and some images of the packed items at http://blufusion.info/lasers/measurements/ for you all to take a look at. Once I post the stuff off, I'll post both tracking numbers too.
I've decided to fork out $50 from my pay (which i actually need to spend on gear for a local show i've been asked to do, but nevermind) to pay for Express Courier International for Sawt's package, so it'll be trackable and is delivered in 3-6 days (IIRC).
Now some more info about the measuring environment.
All measurements are taken using my Coherent 3W thermopile meter (same core components as the Kenometer, but built by myself) and captured and logged with my Digitech USB connected multimeter. Total system error is 3% max.
The test battery was fresh off my Ultrafire WF-139 charger (immediately before each run), and is an UltraFire protected 18650 (grey type).
Room temperature was 18 degrees, taken with a K type thermocouple probe left to sit for 5 minutes.
The green laser's test was 2 minutes, and the IR's was 15 minutes.
Interesting note: After the 15 minutes, the IR was only 27 degrees, barely detectable as warm to touch, but definitely not room temperature / cool.
