Detector Spectral Response Characterisation

The photoelectric detector is today used daily in all walks of life. One of the key measurements of performance is the spectral responsivity of such a detector. The ZLX-DR system is configured to measure spectral responsivity from a series of detectors in the UV to IR spectral range in reference to a calibrated detector. The system comprises of multiple light source options that can be inserted automatically into the light path and also a motorised exchange between the reference detector and the detector under test.

System Configuration

  Detector Responsivity System
Light Sources Deuterium, Tungsten, Xenon, SiC
Monochromators Omni-lambda 300, Omni-lambda 500
Sample Chamber Large Sample Chamber with integrated X-Y motorised positioning stage for accurate and repeatable positioning of reference detectors and detector under test
Detectors Reference detector with calibration file
Data Acquisition Lock-in Amplifier, DCS102,
Software ZolixScan
Options Order sorting filter wheel, Hg spectral calibration lamp, spectral correction lamp, customised illumination optics depending upon requirement of the detector under test, motorised detector exchange unit, motorised light source changer.
