ProMetric I61 Imaging Colorimeter
Description
ProMetric I61 offers the highest-resolution imaging sensor available in tristimulus imaging colorimeters at 61 megapixels (9568 x 6380). This allows the system to maximize the number of sensor pixels applied to measure each display pixel—to ensure measurement accuracy—while still capturing the entire display in a single image—to ensure efficiency. It measures millions of data points, characterizing all pixels in a display in less than 2 seconds. With this speed advantage, manufacturers can apply the ProMetric I61 for production-level applications that include in-line quality control and demura.
ProMetric I imaging colorimeters are designed to address the demands for high-volume manufacturing of displays, backlit components, light sources, and device components. Applying tristimulus color filter technology based on standard CIE color-matching functions, ProMetric I provides highly accurate color and luminance measurements for lab testing and production-level inspection.
Throughout the design and production of light sources and displays, imaging colorimeters are applied to evaluate visual performance based on universal and user-centric light measurement methods. Imaging colorimeters have scientific image sensors and optical filters that allow them to replicate the human eye’s sensitivity to light, following a model of standard human visual perception defined by the CIE (International Commission on Illumination).
The ProMetric I61 provides the foundation for several solutions beyond emissive display testing. The system pairs with several Radiant lens options, including the XRE Lens and AR/VR Lens for measuring displays inside augmented and virtual reality headsets; the FPD Conoscope Lens for view angle measurement of flat panel displays; the Microscope Lens for five to ten-times effective resolution; and standard electronic focus imaging lenses.
Each solution is controlled by a unique TrueTest Software package, developed for a variety of measurement scenarios from AR/VR display testing to automotive head-up display (HUD) characterization.
