Summary[edit]
DescriptionRed-YellowGreen-Blue LED spectra.png |
English: Combined spectra of a common blue LED, a yellow-green LED and a high brightness red LED from the bottom of a Microsoft optical mouse. The spectra have been cleaned up a bit in photoshop to anti-alias the curves but this has not appreciably changed the data to any noticeable degree. I took these spectra on an Ocean Optics HR2000 spectrometer [1]. This spectrum is not calibrated for intensity.
