ELeQuant is designed to support laboratories in the development of semiconductor devices such as LEDs and solar cells. The system is able to measure both absolute photo-emission spectra and IV curves under various electrical and thermal conditions. Spectra are calibrated to NIST-traceable standards via a simple semi-automated procedure.
