Photo Emission Tech., Inc.
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.

LPPHOT03… Series -
Delta OHM S.r.L.
The probe LPPHOT03 measures illuminance (lux), defined as the ratio between the luminous flux (lumen) passing through a surface and the surface area (m²). The spectral response curve of a photometric probe is similar to the human eye curve, known as standard photopic curve V(λ). The difference in spectral response between LPPHOT03 and the standard photopic curve V(λ) is calculated by means of the error f’1.

Inphora Inc.
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:

UVS-B-T -
Kipp & Zonen B.V.
Compared to the spectral response of the UVS-E, the UVS-B-T has a sharper cut-off at the transition from UV-B to UV-A. This feature reduces the UV-A contribution to the radiometer output and permits the highest possible correlation to atmospheric UV-B irradiance.
