Compact ultrafast spectrometers inside LED sorting machines
The lighting industry is rapidly progressing into the new dimensions of opportunity provided by solid-state lighting. Especially Light Emitting Diodes (LED’s) and Organic LED’s (OLED’s) will replace traditional lightning and fluorescent lights in the coming decade. In order to have a uniform lightning it is important that the LED’s that are used are matching in color. These so-called color parameters of LED’s can be determined by a radiometric calibrated fiber coupled spectrometer, such as the AvaSpec-2048-USB2. Important aspect of this application is the speed and accuracy with which the LED’s can be classified. The AvaSpec-2048-USB2 spectrometers can run at a 1.1 ms integration time and a 2ms/scan data transfer time, allowing the LED sorting machine to run at maximum speed.
