New Ocean Optics Measurement System for Quality Inspection of Solar Simulators

(Nanowerk News) Ocean Optics ( has introduced an optical measurement system for absolute irradiance measurements of solar simulators and other radiant sources. The RaySphere enables measurement of absolute irradiance (mW/cm2/nm) over different spectral ranges from the UV to the NIR (380-1700 nm).
RaySphere is especially useful to solar simulator manufacturers and R&D labs as a tool to validate the output of installed solar flash lamps. 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. RaySphere provides a system with the necessary accuracy and resolution to measure and analyze the performance and stability of the flasher, with advanced, ultra-low jitter triggering electronics for timing the measurement to the flashes. The calibration of the RaySphere has been validated by an accredited certification lab to ensure accurate detection, allowing evaluation and qualification of the spectral distribution of solar flashers and simulators according to norms established by standards-setting bodies such as ASTM and IEC (IEC60904-9 2007).
Two thermo-electrically cooled detectors allow highly repeatable and accurate spectral analysis of solar flashers from 380-1700 nm. A second version of RaySphere contains a single cooled detector for measurement to 1100 nm.
The system also includes advanced, high-speed electronics and an intuitive and powerful software interface. Extremely brief measurement times enable the detection of a complete spectrum during a flash or even during a portion of the flash. In addition, the measurement can be triggered by a fast response photodiode that reacts on the increasing intensity of the flashlight with sub-microsecond response times.
