Ocean Optics RaySphere 1700 Install - Manual (Page 12)

1: Introduction
2 RAYSPHERE-1700-02-201304
RaySphere contains one QE65000 spectrometer, while RaySphere 1700 contains two spectrometers
(QE65000 and NirQ512) and a trigger unit to control the measurement procedure and a hub. The trigger
sources can be a flash from the solar simulator, an electrical trigger pulse (high level with +5 V or +24 V)
or a measurement can be generated manually at any time.
RaySphere software allows full control during the testing and generates a test report with the
classification of the simulator.
Photocurrent Recording
A unique innovation for test control is the function photocurrent recording. A photodiode detects the
integral light intensity of the environment. The sudden increase of intensity is interpreted by the
electronics as a measurement event and the complete flash signal is recorded up to 160 ms flash duration.
The time-dependent photocurrent is displayed and the time interval in which the spectrometer has
recorded light from the solar simulator is indicated. The user can adjust delays to make sure that the
recording time of the spectrometer was at the stable flash phase and maximum control for the testing
procedure is given to minimize any kind of mismeasurement.
Calibration
The calibration is tested by an independent certificated optical calibration laboratory. The inaccuracy for
the spectral match as described in IEC 90604-9 is typically on the order of 2 %. Uncertainty has been
minimized to achieve highest precision. A detailed description about calibration and uncertainty is given
in this document.
RaySphere Software
The RaySphere software allows intuitive operation of the system and automatically generates a test report
with classification of the simulator. The software was especially designed for the requirements of the
solar industry.
