Radiant offers dedicated systems for testing illuminated keyboards, keypads, and control panels in high-volume manufacturing environments.


Testing and Quality Control for Computer Keyboards, Laptops, and Mobile Devices

Illuminated keyboards and keypads can exhibit variations in brightness and color from key to key, and even within keys, that are noticeable to the end-user. These flaws detract from the user experience and, in some cases, strongly impacts overall product usability. Radiant offers a dedicated system for automated visual inspection of illuminated keyboards and keypads to measure luminance and chromaticity of individual characters and the overall keyboard. Our PM-KB™ Illuminated Keyboard Testing Software system also performs optical character recognition (OCR), allowing the software to determine if keycaps are installed correctly and each key is in its proper location.


Control Panels

Quality Inspection for Illuminated Control Panels

Makers of control panels found in products that can directly impact safety and health—such as those produced by the automotive, aerospace, and medical equipment industries—must have accurate and reliable test systems for their displays. It is vital ensure the visibility and legibility of illuminated icons and characters. Radiant’s integrated systems measure luminance and detect non-uniformities in keys, switches, indicators, and other controls. Our imaging technology can test multiple keys and characters simultaneously, capturing and processing data much faster and more consistently than a human inspector or a spot measurement device.
