Radiant Vision Systems Introduces New ProMetric® I16-G-SC Imaging Colorimeter & Integrated Spectrometer
REDMOND, Wash. – November 19, 2024
Radiant Vision Systems, a leading provider of image-based light and color measurement solutions, announces its new ProMetric® I16-G-SC, a combination of an imaging colorimeter & spectrometer for complete color measurement in one solution.
ProMetric® I imaging colorimeters are designed to address inspection demands for high-volume manufacturing of displays, illuminated components, light sources, and surfaces. These systems use tristimulus color filters, which provide an innately close response to standard CIE color-matching functions. This enables the most accurate evaluation of color based on the human visual experience (380 nm - 780 nm) to ensure quality as perceived by users of light-emitting devices. With scientific-grade image sensors in a range of high-resolution options, ProMetric® imaging colorimeters can perform subpixel-level measurement of luminance and chromaticity as well as inspect numerous precise details across large fields of view.
In 2022, Radiant Vision Systems introduced its initial ProMetric® I-SC Solution for light and color measurement. This combined the functions of an enhanced ProMetric I61 Imaging Colorimeter from Radiant with a CAS 140D spectroradiometer from Instrument Systems GmbH. Like that model, the ProMetric® I16-G-SC enables efficient measurement of both spectral data and image-based colorimetric data with complete data capture through a central software interface. Radiant’s new solution combines an enhanced ProMetric® I imaging colorimeter—including a scientific-grade, 16.1-megapixel (5312 x 3032) image sensor—with a high-end CAS 125 spectroradiometer from Instrument Systems GmbH to provide accurate, repeatable measurements. The resolution of this system enables pixel-level measurement of LCD, OLED, microLED, and other displays. The ProMetric® I16-G-SC offers a lower resolution system than the current ProMetric® I-SC offering, rounding out Radiant’s portfolio of integrated colorimeter/spectrometer solutions and providing a more cost-effective option to customers. An innovative design, based on patented technology developed by Radiant Vision Systems (US Patent No. 8482652), the ProMetric® I16-G-SC employs a polarization-insensitive mirror, mounted inside the imaging colorimeter on the color filter wheel, to redirect light through a fiberoptic cable to the spectrometer. This solution is optimized for speed, resolution, and measurement accuracy. Using a measurement image acquired by the connected imaging colorimeter, the ProMetric® I16-G-SC simultaneously measures spectral data at the center point while quantifying and comparing spatial luminance (cd/m2) and chromaticity (CIE x,y and u′v′) values across the image to evaluate a device.
Both systems are controlled using a single software platform, which also provides a centralized interface for data visualization and output. From software, users can initiate spectral data capture on demand or program the solution to capture a spectrum automatically with each measurement. Reference spectral data can be applied directly to the imaging colorimeter for in-line color calibration to new devices and device states, ensuring a consistent match between camera response and CIE measurement functions. As a directly integrated system, ProMetric® I16-G-SC operates continuously without intervention, ensuring repeatable accuracy, efficiency, and ease of use.
“Since combining the functions of an imaging colorimeter and integrated spectrometer in 2022, we’ve grown our partnership with world-leading expertise in spectrometers and expanded on our existing technology to focus on the specific needs of the customer when it comes to the resolution, features, and price point best suited to them,” states Stone Jiang, CEO of Radiant Vision Systems. “The ProMetric® I16-G-SC offers a 16.1MP, providing pixel-level measurement of displays, inter- and intra-character luminance measurement of backlit keyboards and panels, and measurement of LED luminance and color from single diodes to large arrays. This delivers the required performance our customers require for highly accurate color and luminance measurements in an automated manufacturing environment.”
ProMetric® I-SC colorimeters can be fitted with a microscope lens and are optimized to work with industry-leading TrueTest™ Automated Visual Inspection Software from Radiant Vision Systems. TrueTest™ provides a complete turnkey solution for production-level test sequencing using a library of light measurement and inspection software tools. From absolute accuracy in product design to optimal efficiency for in-line quality control, the ProMetric® I16-G-SC Solution is engineered specifically to address end-to-end metrology applications.
