Abstract :
Why is wavelength detection important? There are many different fields where detection of the colour or the wavelength of objects - in our case, LEDs - is interesting. These areas include the consumer market, the automotive sector and the industrial sector. For example, more and more LED backlights are being used for display equipment and for such displays to maintain accurate colour rendition, it is mandatory to monitor the wavelength of these LEDs. One other possible application is the use in the LED lighting sector to provide a possibility to detect and compensate for colour changes due to temperature effects.
