    Spectroradiometer For Detector Characterization

    Sciencetech Spectroradiometer

    Spectroradiometer Overview


    Sciencetech offers modular spectroradiometer system with high light throughput and minimal stray light. The system allows spectral characterization and calibration of ultraviolet, visible and infrared spectrum using UV-Vis and Infrared array detectors.

    A cosine correcting optics with a near cosine response between intensity transmitted and angle of incidence at the integrating optic allows the highest possible throughput. A fiber optic is used to allow for more convenient placement of the integrating optics in the area to be tested.  Optical and electronic gates are used to integrate discrete temporal component of the light pulses to the spectral dispersion system. The light pulse and detection system synchronized using triggering electronics and results in very low integration time (0.5 ms).  The spectral dispersion system efficiently transmits the required spectral bandpass to the array detectors.  There is a separate spectral dispersion system for UV-VIS and IR systems 

    Spectroradiometer Applications

    • Pulsed Solar Radiation Measurement

    • Solar simulator testing and classification

    • Light source metrology

    Sci -Vidi time resolved spectroradiometer provides advanced characterization tool for pulsed solar simulators. Solar simulators with different technical specification are designed to fit specific application, and are generally divided into two categories continuous or steady-state and pulsed. The continues type is mostly used for low intensity of one up to several suns. The pulsed version has flash/pulse of typically few milliseconds and it is commonly used for high intensity testing of up to several thousand suns. For second type, pulsed spectroradiometers synchronised with pulse of solar simulators are critical for spectral irradiance analysis.

    Accurate measure of radiometric quantities is essential requirement for manufactures of solar simulators and solar devices such as solar cells, panels, and modules. The manufactures have to validate compliance to spectral requirements. Generally, solar simulator should be tested for uniformity of power distribution, spectral match and temporal instability. Calibrated spectroradiometers measure spectral irradiance and facilities simulator classification.

    Sci-Vidi includes a NIST-traceable irradiance calibration to ensure accurate and consistent measurements and it complies with ASTM G 138-12(Standard Test Method for Calibration of a Spectroradiometer Using a Standard Source of Irradiance). All components of the system designed to transmit 300-2000 nm efficiently.

    The SciVidi spectroradiometer is an integrated spectrordadiometer system designed to measure bot AC and continuous wave light sources such as solar simulators over a wide spectral range.
    The standard SciVidi system includes two spectral dispersion systems with integrated diode array detectors for measuring spectral irradiance from 300-2000nm. The SciVidi is calibrated for spectral irradiance with a Deuterium and calibrated quartz tungsten halogen lamp. The spectroradiometer can measure spectral irradiance in time intervals as short as 500uS and can be synchronized with a TTL pulse. A cosine corrected optical head is connected to the spectroradiometer by a 2m fiber optic.

    For a system that meets your specific requirements please contact a Sciencetech technical sales representative.
