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.

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.

Software

The PCS300 may be controlled over the USB 2.0 interface using our Windows application Benwin+ or by user written code based on our SDK on a wide range of platforms (Labview, Matlab, C++ etc.) Using configuration files, both applications allow: 

  • Accessing grating filter wheel and slit properties
  • Wavelength selection
  • Spectral measurements

Benwin+ includes higher functionality including:

  • Easy system calibration
  • Obtain spectrally integrated (and weighted) quantities
  • Instantly obtain colorimetric data
  • Perform transmission, absorption and reflection measurements
  • Perform simple arithmetic functions
  • Utilities for control of translation stages, goniometers, RSB, data acquisition from other instruments etc.
