Measure the ion energies and ion flux impacting on your substrate with our RFEAs - rapidly characterise your plasma chamber under different power, pressure, frequency and gas flow conditions.
Our high performance Octiv VI probe can measure RF power with 1% accuracy, as well as measure impedance and RF harmonics to get a direct view of your plasma.
Measure the fundamental plasma parameters such as the ion density, electron temperature and plasma potential with our state-of-the-art Langmuir Probes

The Alfven is designed to detect arcing in RF plasmas with 1 microsecond resolution.
The Langmuir Spatial can map out the ion density with 1 mm resolution across your plasma chamber, rapidly mapping uniformity under different process conditions
The Octiv Mono can be used to characterise the power efficiency and impedance range of match boxes.
The Quantum RFEA is a hybrid between an ion energy analyser and quartz crystal microbalance, enabling it to directly measure the ion/neutral ratio impacting a substrate surface. This is one of the key parameters for transferring thin film processes between different tools.
