Recently, Radiant Vision Systems announced the launch of its latest solution, the ProMetric® I16-G-SC, which combines a colorimeter and a spectrometer to offer comprehensive color measurement capabilities.
Meeting High-Volume Production Needs
The ProMetric® I colorimeters are designed to meet the demands of high-volume production for displays, light-emitting devices, light sources, and surface inspections. These systems use tristimulus color filters, closely matching the response of the standard CIE color matching functions. This allows them to simulate the human visual perception of color (380 nm – 780 nm), ensuring the most accurate color assessment for light-emitting devices.
High-Resolution Measurement Technology
With scientific-grade image sensors, ProMetric® colorimeters offer a range of high-resolution options capable of performing sub-pixel measurements of brightness and chromaticity, detecting precise details over large field-of-view areas.
In 2022, Radiant Vision Systems introduced its first ProMetric® I-SC solution, combining the enhanced ProMetric I61 colorimeter with the CAS 140D spectrometer from Instrument Systems GmbH.
New Capabilities in the ProMetric® I16-G-SC
Like its predecessor, the ProMetric® I16-G-SC enables efficient measurement of spectral and image-based chromaticity data via a centralized software interface, offering complete data acquisition. The new solution integrates an enhanced ProMetric® I colorimeter (featuring a 1610-megapixel (5312 x 3032) scientific-grade image sensor) with the high-end CAS 125 spectrometer from Instrument Systems GmbH for precise and repeatable measurements. The system’s resolution allows for pixel-level measurements of LCD, OLED, Micro LED, and other displays.
Cost-Effective and Efficient Option
The ProMetric® I16-G-SC provides a more cost-effective option for customers, offering a lower-resolution system than the current ProMetric® I-SC, expanding Radiant’s colorimeter/spectrometer integration solution portfolio.
Optimized Design for Speed and Accuracy
The ProMetric® I16-G-SC features an innovative design, based on Radiant Vision Systems’ patented technology (US Patent No. 8482652), utilizing a specialized lens mounted on an internal color filter wheel within the colorimeter. This directs light through an optical fiber cable to the spectrometer. The solution has been optimized for speed, resolution, and measurement accuracy. The ProMetric® I16-G-SC uses images captured by the connected colorimeter while measuring the spectral data at the center point, quantifying and comparing the spatial luminance (cd/m²) and chromaticity (CIE x, y, and u′v′) values across the entire image to assess the device.
Centralized Software Interface for Efficiency
Both systems are controlled by a single software platform, which also provides a centralized interface for data visualization and output. Users can initiate spectral data capture through the software on demand or program the solution to automatically capture spectra with each measurement. Reference spectral data can be directly applied to the colorimeter for online color calibration of new devices and devices in operation, ensuring consistency between the camera response and CIE measurement functions.
Seamless Operation with Continuous Accuracy
As a fully integrated system, the ProMetric® I16-GSC operates continuously without intervention, ensuring repeatable accuracy, efficiency, and ease of use.
Customer Benefits in Automated Environments
“Since 2022, when we first combined colorimeters and integrated spectrometer functionality, we have partnered with world-leading spectrometer experts and expanded our existing technology to meet customers’ specific needs in resolution, functionality, and price,” said Stone Jiang, CEO of Radiant Vision Systems. “The ProMetric® I16-G-SC, with its 1610-megapixel resolution, allows for pixel-level measurements of displays, brightness measurements for backlit keyboards and panels, and brightness and chromaticity measurements of LED arrays ranging from single diodes to large arrays. This provides our customers with the performance needed for high-precision color and luminance measurements in automated production environments.”
TrueTest™ Software Integration for Optimal Quality Control
The ProMetric® I-SC colorimeter can also be paired with a microscope lens and optimized for use with Radiant’s TrueTest™ automated visual inspection software. TrueTest™ provides a comprehensive set of optical measurement and inspection tools for production-grade testing sequencing. From precise product design to optimal efficiency in online quality control, the ProMetric® I16-G-SC solution is designed for end-to-end metrology applications.
