Photometer characterisation solution

PCS300 from Bentham

The PCS300 provides accurate characterisation of key parameters relating to the performance of luxmeters, luminance meters and components.

Set around a tuneable monochromatic light source, the PCS300 enables the spectral responsivity measurement of photometers to determine their deviation from the desired CIE V(λ) function, represented by the f1’ mismatch index. Furthermore, product development is empowered by the possibility of measuring the component detectors and filters of photometers, ensuring blocking out of band. The addition of a motorised goniometer allows the measurement of directional response.

Features
  • Xenon lamp/ single monochromator tuneable light source
  • Dual optical path optic to couple light to DUT and reference photodiode for parallel measurement (luxmeters)
  • Integrating sphere accessory for characterisation of luminance meter spectral mismatch
  • Collimated deuterium/ halogen source option for measurement of filter transmission
  • Motorised single axis goniometer with manual DUT 90° rotation for directional response measurement
  • Calibration traceable to Physicalish Technische Bundesanstalt (PTB, Germany

Further information

Easy to use, the PCS300 will directly report the values important to demonstrate the performance of your photometers. Compliment the PCS300 with the LuxCal250 for the calibration of lux and luminance meters according to ISO/CIE 19476:2014.
