With a resolution enabling pixel-level measurement of displays, 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 I16-G is the latest addition to the Radiant Vision Systems line of ProMetric Imaging Colorimeters.
The I16-G is a 16.1-megapixel image sensor, offering a midrange resolution that rounds out Radiant’s I series line. Source: Radiant Vision SystemsProMetric 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 (HUDs), Radiant said. Imaging enables ProMetric systems to capture millions of data points simultaneously across a single field of view for extremely rapid measurement cycles. Imaging also allows spatial comparison of data points across the field of view — something necessary for evaluating brightness or color uniformity, gradient, contrast, pixel-level variation, random defects, and dimensional accuracy of light source distributions and displays.
The new I16-G uses a scientific-grade, 16.1-megapixel (5312 x 3032) image sensor to provide accurate, repeatable measurements, offering a midrange resolution option to round out Radiant’s I series line. The I series is designed to address the demands of high-volume manufacturing of displays, backlit components and light sources, and currently includes options ranging from 2MP to 61MP.
“When it comes to light and color measurement solutions, the importance of capturing critical details in any device is essential,” said 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.”
Kreysar said that flat-field correction is automatically applied by the colorimeter’s electronically controlled focus and aperture, reducing setup time and providing manufacturers with more precise measurements.
“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,” Kreysar said.
News of the I16-G comes on the heels of Radiant’s recent release of a microscope lens that mounts directly to an imaging colorimeter or photometer, enabling either device to focus a greater number of image sensor pixels per display pixel for fine-detail measurement.
