Quantum Efficiency Measurement System, 350-1100 nm Wavelength Range

The IQE-200B leverages 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). This model has been integrated with the redesigned Cornerstone 130B monochromator to provide upgraded performance while maintaing the same functionality and system platform. Scan speeds have nearly doubled, cutting measurement times in half!

The IQE-200B empowers researchers to measure Internal Quantum Efficiency (IQE) and quantify External Quantum Efficiency (EQE), also known as Incident Photon to Charge Carrier Efficiency (IPCE), for any photovoltaic device. Employing industry leading, durable components for optical performance, the IQE-200B is preconfigured, assembled, and calibrated at the factory. The product is a turn-key solution which includes all necessary components with integrated light source, monochromator, Silicon detectors, electronics, software, and even the computer.

The IQE-200B incorporates a patented detector geometry using a beam splitter, allowing for simultaneous measurement of EQE and the reflective losses to quantify IQE. Unique to this model is an integrated, software-controlled sample voltage bias, adjustable from -10 to +10V. This model also includes a 4-wire sense which broadens the capabilities to include a large range of sample sizes and efficiencies. A variety of accessory models are available to provide positive sample positioning, temperature control, and electrical probing capabilities.
