Cen-Tech IR thermometer
Aixiz module

For the red tests:
The heat sink you sent me
Aixiz red AR coated glass lens

For the non-cooled violet test:
The heat sink you sent me
Aixiz 445 glass lens

For the cooled violet test:
Aixiz heat sink (the loose extruded-Al kind)
40W TEC
CPU heatsink and fan
Aixiz 445 glass lens and later switching to acrylic and later wiping the acrylic with an anti-fog wipe

Like I said, you should probably disregard the power graph for series 1 violet because of the condensation.

The procedure was rather unremarkable, but went something like this:
hook everything up and turn power on
Start at lowest setting of 50mA.
take measurements (current, voltage, wavelength, power)
A few times: turn up current and take measurements again
turn off power for a while to keep temp as low as possible
turn on power and resume
