High Brightness, Broadband Calibration Source


Stable Radiometric Calibration 

EQ-99X-CAL reaches past spectral range limitations and covers the full UV-Visible range.

Traditional calibration sources for radiometric calibration, such as Deuterium, Quartz Tungsten Halogen, and Xenon-arc, all have limitations in spectral range. None of these standard sources covers the full UV-Visible range from 200 nm-800 nm with output at comparable levels across that spectrum. Additionally, traditional sources require recalibration after 100 hours or less of use and lamp replacement typically after 500 hours. With its revolutionary Laser-Driven Light Source™ (LDLS), Energetiq offers a calibration solution that addresses these limitations and provides a single, broadband, high brightness source for radiometric calibration.

The EQ-99X-CAL combines radiometric performance with long life, longer recalibration intervals, and low cost of ownership. Calibrations made in the 350 nm range are particularly challenging with Deuterium and Quartz Tungsten Halogen lamps. In the case of Deuterium lamps at 350 nm, the irradiance is approximately an order of magnitude lower than its value in the deep UV at 200 nm. Similarly, Quartz Tungsten Halogen lamps at 350 nm are more than an order of magnitude lower in irradiance compared to their value in the visible range.

It can be problematic to have the two separately calibrated lamps agree at the overlapping wavelengths. With the LDLS, a single calibrated light source covers the whole range from 200 nm to 800 nm, and at 350 nm exhibits an irradiance an order of magnitude higher than traditional calibrated Deuterium and Quartz Tungsten Halogen lamps.

Energetiq’s EQ-99X-CAL product is calibrated at our calibration partner, Bentham Instruments, Ltd. Bentham’s calibration standards are traceable to the Physikalisch-Technische Bundesanstalt (PTB) in Germany. A certificate of calibration, which comprises the calibration data and the uncertainty analysis, is included with each EQ-99X-CAL. Sample calibration reports are available upon request.
