File:Red-YellowGreen-Blue LED spectra.png

Summary
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. This spectrum is not calibrated for intensity.
