RaySphere Solar Analysis System
Meet the new optical measurement system for absolute irradiance measurements of solar simulators and other radiant sources. The new RaySphere from Ocean Optics measures absolute irradiance over spectral ranges from the UV to the NIR (350 to 1700 nm).
This portable system is ideal for solar simulator manufacturers and research and development labs as a tool to validate the output of installed solar flashlamps. The flash of a solar simulator is used within the photovoltaic (PV) manufacturing process for the binning of cells according to spectral response and for final PV module efficiency measurements.
The RaySphere system delivers the accuracy and resolution needed to measure and analyze the performance and stability of the flasher with ultralow jitter triggering electronics for timing the measurement to the flashes. Calibration has been validated by an accredited certification lab to ensure accurate detection, enabling evaluation and qualification of the spectral distribution of solar flashers and simulators according to the IEC60904-9 (2007) standard.
The system includes two thermoelectrically cooled detectors that perform repeatable and accurate spectral analysis of solar flashers from 350 to 1700 nm, and a second version contains a single cooled detector for measurement to 1100 nm.
RaySphere includes high-speed electronics and an intuitive powerful software interface. Brief measurement times enable detection of a complete spectrum during a flash or even during a portion of the flash. The measurement can be triggered by a fast response photodiode that reacts on the increasing intensity of the flashlight with sub-microsecond response times.
