Oriel Quantum Efficiency System Set Up Demonstration

Getting any quantum efficiency system up and running is a straightforward process, as demonstrated in this video.

Sophisticated Technology

These products leverage Newport's expertise in optical design, spectroscopy, precision motion control, and electronics technologies. These proficiencies have been focused into a complete, sophisticated measurement system for Quantum Efficiency (EQE and IQE). Both systems incorporate a patented detector geometry using a beam splitter, allowing for simultaneous measurement of EQE and the reflective losses to quantify IQE. Unique to these models are a sample stage with an integrated vacuum chuck and thermistor. They also include 4-wire sense measurement option which broadens the capabilities to include a large range of sample sizes and efficiencies.

Intuitive Software

The acquisition and controls software for these QE solutions is pre-installed on a laptop computer which is included with the measurement system. The software uses an intuitive, icon based graphical interface to provide instrument controls, configuration, and data acquisition. The software seamlessly controls all of the system components. EQE and IQE curves are calculated and plotted as a function of wavelength in a single scan without the need to reposition the detectors or sample, optimizing measurement accuracy and repeatability. There is also an integrated, software-controlled sample voltage bias feature, which allows users to adjust from -10 to +10V.
