My latest photometer test involved a 660nm ultrabright red LED and an orange LED. Forest Mims explains there is an ozone band that covers the red LED. So far I see that the temperature coefficients of both LEDs is positive. So that's what I expect. I'll need to get a serious chill on the photometers to get a handle on their temperature coeeficents. Then I'll be ready to launch them into near space. Check my blog for charts soon.
