Imaging Colorimeter with Integrated Spectrometer

The ProMetric I-SC Solution for light and color measurement combines an imaging colorimeter and an integrated spectrometer. In one device, it enables measurement of both spectral data and image-based colorimetric data with complete data capture, analysis, output, and calibration functions controlled through a central software interface.

It applies a polarization-insensitive mirror to enable direct integration of a ProMetric I Imaging Colorimeter and a CAS 140D spectroradiometer; this integrated solution captures two pieces of a complete measurement at once: the CAS 140D measures highly accurate correlated color temperature and color rending index while Radiant’s high-resolution ProMetric I61 (61-megapixel) Imaging Colorimeter measures precise luminance and chromaticity data for all points in an image—including regions as small as a display subpixel.

Direct integration also facilitates calibration of the connected imaging colorimeter for measuring new devices or device status. A calibration function can be initiated as needed to capture and apply spectral data from the spectrometer to align the imaging colorimeter’s response to standard CIE color-matching functions for highly accurate, repeatable measurement of a source.
