Radiant Vision Systems provides visual test and measurement systems that characterize and inspect light and color for quality in display design and automated production. Their inspecting processes and tools are used in LCDs, LEDs, microLEDs, and OLED for flat panel displays, head-up displays, AR/VR, and near to eye displays (NEDs).
Machine vision inspection has been a boon to many industries—from electronics to packaging to medical devices—by automating repetitive quality inspection tasks. However, traditional machine vision systems simply cannot equal the precision and judgement of human inspectors when it comes to examining low-contrast features, for example, or assessing the scope and severity of defects. Machine vision systems may miss a large percentage of defects in challenging applications like inspec
Today’s electronics manufacturing processes are largely automated. However, final inspection for connected assemblies has lacked an effective automated solution that achieves both highly-repeatable and highly-accurate defect detection. At the final stages of production where internal components are verified before device enclosure, human inspectors remain the primary inspection method.
Are you facing a tough visual inspection challenge with your devices? Looking for a better way to prevent escapes, latent failures, and product returns?
Today’s electronics customers expect flawless device quality right out of the box, and that holds just as true for keyboards as it does for smartphones or televisions. Device quality is paramount—just ask this Reddit user, who posted a complaint about tiny cosmetic defects on a keyboard.
The more complex an assembly, the greater the chance an error will occur during production—and, the more challenging it becomes to visually verify assembly integrity. Standard machine vision systems (commonly offering one- to five-megapixel sensors) are unable to capture images at a high enough resolution to detect all defects in a complex assembly such as an electromechanical device.
There’s an old saying: “the devil is in the details.” When it comes to assembly verification in complex electromechanical devices such as smart phones, laptops, and keyboards, that saying couldn’t be more true. Even a tiny defect such as a loose connector or slightly misrouted cable can cause problems. A defective unit may not be caught until final assembly or functional test at the end of the production process, resulting in rework and wasted time or materials.
Photometry-based assembly verification performs better than typical machine vision or human inspectors when it comes to catching subtle defects in complex electromechanical assemblies, helping decrease your rate of escapes and latent product failures. Radiant’s INSPECT.assembly solution can detect and prevent misrouted cables, missing screws, or misaligned connectors that could pinch, detach, or loosen with use, resulting in failures after products ship.
Robots are getting better at doing more and more tasks—from devices that vacuum our homes, to drones that deliver packages, to robotic arms that help build automobiles. But one thing machine systems haven’t been able to do well until recently is match the acuity of human vision. Precise visual assessment is particularly important for inspecting products like electromechanical devices.
Photometric imaging solutions bridge the gap between machine vision systems and true human vision, offering consistent, quantifiable data that matches the visual acuity of human inspectors.
Advanced imaging offers a number of advantages not currently met by standard machine vision or human inspection in electronics assembly verification. The INSPECT.assembly system from Radiant integrates our highest-resolution imaging systems with lighting and software together in a single turnkey fixture that easily rolls onto conveyors for in-line evaluation of connected assemblies before device enclosure. In this presentation, you will learn about:
The INSPECT.assembly solution is a fully-integrated inspection station that utilizes a Radiant Vision Systems imaging photometer, bright field lighting, and programmable software to detect subtle defects on complex assemblies and low-contrast parts and surfaces.

In this article, learn how photometric and colorimetric technology matches the visual sensitivity of human vision. We discuss the advantages and applications of CCD imaging for light and color measurement, as well as component and surface inspection, that most accurately reflects the human visual experience.
To succeed in the electronics industry, you have to stay at the forefront of technology. The annual IPC APEX EXPO in San Diego is the place to be this week (Feb 27-March 1) if you want to see the latest product developments for PCB and electronic device manufacturing, and solutions that give manufacturers an edge in productivity and quality.
“Hard” inspection problems are ones that push the limitations of any visual inspection method—human or machine. As electronic and mechanical devices become more complex, assembly verification requires inspection of multiple features simultaneously and at high speed. Complex assemblies can contain many small parts or low-contrast elements that are difficult to assess at production speeds.
Human visual perception is the ultimate standard of quality for any lighting or display product that’s intended to be viewed by humans. No machine vision or other sensing system has been able to fully replicate the level of discernment and accuracy of the human eye, but we can get very close using CCD-based imaging technology.
Engineered with the acuity to measure subtle variations in light and color, Radiant’s advanced vision systems are uniquely capable of detecting small, subtle flaws in assemblies and surfaces that are easily missed by traditional machine vision systems. In this video, you will see:
