We detected and compared the transmission spectra and reflection spectra of the filter glass and leafs with the spectrofluorimeter and spectrophotometer.
In this paper, the importance of the interference filter's monochromatism for realizing high singal-to-noise ratio and its application in the biochemical instruments,are described in detail.
This oscillation is important, because you can limit what light passes through a filter, depending on which direction its electric field is oscillating in.
I'm sure they'll ship one, but the idea here is that OLED is a little bit dimmer than it needs to be because it has to shine the light through a filter.
