Light Measurement Applications

Radiant’s photometric imaging systems measure light and color in displays, illuminated keyboards, backlit panels and components, LEDs, and other light sources. Our imaging colorimeters and photometers are applied across industries to quantify and evaluate light-emitting devices for a range of values including: luminance, illuminance, luminous intensity, total luminous flux, CIE chromaticity, correlated color temperature (CCT), light and color uniformity, and contrast. These values can be used in device characterization and design in lab settings, and compared against production values for quality control on the line.

Radiant’s comprehensive display test solutions address the latest LCD, LED, and OLED technologies in smart devices and embedded displays, head-up displays, and near-eye displays, while our light source measurement systems provide high-accuracy characterization of LEDs and luminaires. Featuring high-resolution, low-noise CCDs and flexible sequencing software, our systems are the leading choice for high-volume production applications, helping manufacturers to improve supply chain performance, reduce production costs, and ensure a flawless end product.
