QUESA-1200 is dedicated to small active area (< 1cm²)

The QUESA-1200 has the great advantage to be easyily integrable in a glove-box thanks to its compactness. The measurement method and system is compliant with the norm ASTM E1021-15 and IEC 60904-8 related to spectral responsivity measurement method of a photovoltaic device.
Other great advantages of using the LED is the possibility to integrate easily Solar Simulator option within the same equipement used fro EQE. All our QUESA and QUESMA Systems have an I-V option with solar simulator according to IEC 904-9 norm.
