This was interesting...
Has anyone noticed a difference in measurement when the sensor is tilted so that its not perfectly perpendicular to the emission source? I wonder if the sensor was tilted in one of these tests, or was positioned in such a way to receive photons of a different trajectory?
I wonder if it's just that the black corded PS produces more power? In the pic below there's almost 2 identical reflectors used but a rather significant difference in measurements. If the black cord PS produces more power then perhaps that's why the un-reflected tube from above is more intense than the semi reflected tube??
1 has a rectangular reflector running behind it and 1 has nothing that it reflects off of. I'd assume that the un-reflected would be less intense but these results flip that assumption.Has anyone noticed a difference in measurement when the sensor is tilted so that its not perfectly perpendicular to the emission source?
