Spectral Response SystemsQuantum Efficiency SystemsIPCE Measurement Systems
QE system provides electronics and software designed for fully automated measurement of external quantum efficiency of solar cells. All systems include probes and a fixed plate sample stage for samples up to 150 mm x 150 mm. The main system components include: custom designed software, measurement electronics, and computer system (Windows 8 operating system). The measurement involves focusing monochromatic light to a spot on the device under test, then accurately measuring the photon flux and current from the test cell. The system utilizes a dual beam configuration with lock-in detection, providing an absolute accuracy of ±3%. The QE system uses a grating monochrometer with silicon/InGaAs/Ge detectors. The system includes automatic order sorting filters and two light sources for monochromatic illumination (a Xenon- arc lamp and a halogen lamp). A single lock-in amplifier is used to measure both the reference detector and test device. The main system comes with all the hardware needed to measure quantum efficiency, a fixed plate sample stage and probes.

Complete Testing Solutions
System includes a lamp and monochromator for a tunable light source, which is coupled to a high sensitivity source meter with measurement software. This user-friendly system is the most powerful Spectral Response system currently on the market, but its true power is the ease of upgrading from the base PTS-1 to the more powerful PTS-2-QE (Quantum Efficiency) or PTS-3-CPM (Constant Photocurrent Method). Designed for researchers who have limited budgets but want to start work immediately, this allows the ability to do baseline studies until additional funding for the full QE or CPM system becomes available.

Custom Detectors
Besides the described types Inphora can supply detector-filter combinations with parameters matching the customer's special requirement, with different sized housing, without housing. If the application determines the detector's spectral responsivity, we can achieve that with a filter designed exactly to the specifications. CCD cameras with unusual spectral sensitivity functions can be matched with filters to obtain CIE tristimulus response or photopic response. Similarly, photmultiplyers can be matched also with INPHORA filters. When determining parameters for a custom detector-filter combination several details have to be considered:
