EXFO X-Cite® Radiometer
calibrated illumination - for absolute repeatability
Where critical quantitative measurements of intensities over time are critical, the X-Cite® Radiometer enables affordable and continuous calibration of the X-Cite exacte broad spectrum fluorescence illuminator attaining the ultimate degree of illumination repeatability, stability, control and consistency.
Furthermore, the X-Cite® Radiometer can be used to test light guide transmission and lamp output of the other X-Cite® 120 series illumination systems.

As the output of any mercury lamp will fluctuate and gradually diminish over time, when working in relative units this means intensity settings are not easily repeatable. The X-Cite Radiometer permits the researcher to calibrate the illumination in watts achieving repeatable intensity levels and consistent results. The Radiometer works with the Closed-Loop Feedback circuitry of the X-Cite exacte to continuously measure the lamp output energy. A microprocessor within the X-Cite exacte responds to automatically adjusts the neutral density wedge "iris" within to maintain the desired set point in 1% increments!
The illumination intensity can be adjusted up or down in absolute power levels (watts) and this setting is displayed on the X-Cite exacte panel or remotely via computer.
This CLF function permits consistency of illumination over seconds, hours, days or even a comparative over months - for the life of the lamp. Even after changing lamp modules the system within the calibrated X-Cite exacte can resume to automatically restore and maintain the desired level.
This is more than a comparatively simple power meter, the X-Cite® Radiometer is designed so that X-Cite® Light Guides communicate directly with X-Cite® X-Cite exacte. This is calibrated using a certified transfer standard, traceable to the US National Institute of Standards and Technology (NIST).
