Ocean Optics RaySphere User Manual

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 ashlamps. The ash of a solar simulator is
used within the photovoltaic (PV) manufacturing
process for the binning of cells according to
spectral response and for nal PV module
eciency measurements.

The RaySphere system delivers the accuracy and
resolution needed to measure and analyze the
performance and stability of the asher with
ultralow jitter triggering electronics for timing the
measurement to the ashes. Calibration has been
validated by an accredited certication lab to
ensure accurate detection, enabling evaluation
and qualication of the spectral distribution of
solar ashers and simulators according to the
IEC 60904-9 (2007) standard.

RaySphere

Solar Simulator Analysis Made Easy

RaySphere includes high-speed electronics and an intuitive powerful software
interface. Brief measurement times enable detection of a complete spectrum
during a ash or even during a portion of the ash. The measurement can be
triggered by a fast response photodiode that reacts on the increasing intensity
of the ashlight with sub-microsecond response times.

Features

- Intuitive graphical interface

- Graphical and table display of classication results by wavelength bin

- Output of actual spectra in mW/cm^2/nm

- Output of actual measurement and triggering timing with +/- 41 µs
resolution

- Printable classication report
