 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 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.
