Radiant Vision Systems introduces new imaging colorimeter

Radiant Vision Systems has announced the new ProMetric I45 Imaging Colorimeter, designed for in-line inspection of displays, backlit components, light sources, and assemblies.

Optimized for efficiency, resolution, and measurement accuracy, the ProMetric I45 provides global shutter imaging with high readout speed and supports high-speed 10 Gigabit ethernet communications. Use of a scientific-grade, 44.7-megapixel CMOS sensor enables pixel-level measurements of displays, inter- and intra-character luminance measurements on backlit keyboards and panels, and accurate measurements of LED luminance and color in luminaires with large LED arrays. This offers a flexible system, capable of addressing multiple applications for lit and non-lit components to provide accurate, repeatable measurements.

“Image-based metrology continues to demand higher and higher imaging resolution to capture more precise, critical details in devices of any shape or size,” said Doug Kreysar, CEO of Radiant Vision Systems. “For the most effective metrology, the goal is to capture the entire device under test within a single image while continuing to measure all its constituent features. Increasing resolution helps us evaluate larger regions, such as LED screens, while continuing to measure the brightness and color of each individual diode. It also allows us to measure millions more tiny light-emitting elements simultaneously across a smartphone or microdisplay to ensure pixel-to-pixel uniformity. A high-resolution imaging system can capture larger and more multifeatured displays or backlit components while still enabling us to perform unique evaluations for each illuminated symbol or shape at once.”

CIE-matched color filters and neutral density filters enable the ProMetric I45 to closely match human visual perception. The ProMetric I45 is optimized to work seamlessly with Radiant Vision Systems’ TrueTest Automated Visual Inspection Software. TrueTest provides a complete, turnkey solution for production-level test sequencing using a library of light measurement and inspection software tools.
