Raysphere, Solar simulator analysis made easy

The New 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 
IEC 60904-9 (2007) standard.
The system includes two thermoelectrically cooled 
detectors that perform repeatable and accurate 
spectral analysis of solar flashers from 350 to 
1700 nm. 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.
