The ProMetric I16-G Imaging Colorimeter is part of Radiant’s ProMetric I family of imaging colorimeters which are used for testing of high-volume manufacturing of displays, backlit components, and light sources.

More broadly, its ProMetric imaging metrology solutions are used to measure properties of light that influence the visual quality of devices such as LEDs, displays, augmented and virtual reality (AR, VR) projections, and head-up displays (HUD).

According to Radiant, its ProMetric devices are able to capture millions of data points simultaneously across a single field of view for extremely rapid measurement cycles, with the imaging also enabling spatial comparison of data points across the field of view, necessary for evaluating brightness or color uniformity, gradient, contrast, pixel-level variation, random defects, and dimensional accuracy of light source distributions and displays.

“When it comes to light and color measurement solutions, the importance of capturing critical details in any device is essential,” states Doug Kreysar, CEO of Radiant Vision Systems. “ProMetric I-series imaging colorimeters, and the electronically controlled lenses supplied with them, are factory-calibrated over all possible distances and two specific aperture settings.

“Because the lenses are electronically controllable for focus and aperture, the colorimeter will automatically apply the appropriate flat-field correction. This reduces set up time and provides more precise measurements for manufacturers. Additionally, high-speed and high-resolution image sensors, along with a flexible system, helps us evaluate larger regions, while continuing to measure the brightness and color of each individual diode.”

According to Radiant, the ProMetric I16-G Imaging Colorimeter uses a scientific-grade, 16.1-megapixel (5312 x 3032) image sensor to provide accurate, repeatable measurements.

The device can be used for pixel-level measurement of displays (LCD, OLED, microLED, and others), inter- and intra-character luminance measurement of backlit keyboards and panels, and measurement of LED luminance and color from single diodes to large arrays. The company said that the new 16.1MP option provides a mid-range resolution option to round out Radiant’s I series line which includes options ranging from 2MP to 61MP.
