| The results of our spectrometer were compared to those of the LED specification sheets. The blue corresponded to a mean peak of 464 nm (-17 nm deviation), the red corresponded to 645 nm (-5 nm deviation), the yellow to 591 nm (-24 nm), and the green to 515 nm (-46 nm). This deviation was due the diffracted light arriving at the photodiode from different angles. This results in a wavelength distribution that is nonlinear across the spectrum. | The results of our spectrometer were compared to those of the LED specification sheets.

| - | The purpose of this project was to differentiate the colours of four LEDs. Our final design has demonstrated that it can indeed differentiate between: red, blue, yellow, and green. Therefore the spectrometer had successfully performed the task the group had intended. | + | The purpose of this project was to differentiate the colours of four LEDs.
