ProMetric® I61 (61-Megapixel) Imaging Colorimeter

17 May 2021

ProMetric I is designed to address the demands for high-volume manufacturing of displays, backlit components, light sources, and assemblies. Whether expanding test coverage or increasing throughput, ProMetric I delivers the required performance for highly accurate color and luminance measurements in an automated manufacturing environment.

The ProMetric I61 is designed around a scientific-grade 61-megapixel (9568 x 6380) CMOS image sensor. This sensor enables pixel-level measurements of displays (LCD, OLED), inter- and intra-character luminance measurements on backlit keyboards and panels, and accurate measurements of LED luminance and color in luminaires with large LED arrays.

Applications:

Display Testing
Used for precise measurement of qualities of light and color across a display, the ProMetric I Imaging Colorimeter captures quantifiable values of spatial luminance, contrast, uniformity, and chromaticity (in CIE x, y and u’, v’). The system can also detect defects like mura, light leakage, and dead pixels or lines in any area of the display.

ProMetric I captures comprehensive luminance and chromaticity values of each display, with analyses applied in a matter of seconds. Equipped for USB and Ethernet communications, the ProMetric I provides highly reliable operation for production operations from camera to camera and line to line, making it the solution of choice for global display panel production manufacturing operations.

Automotive Systems
Light, color, and dimensional accuracy are key for visual performance, regulatory compliance, and consumer satisfaction of all illuminated elements inside and outside the vehicle, from instrument panels and dome lights to headlamps. Paired with automated analysis software from Radiant’s TrueTest platform, the ProMetric I offers the complete measurement solution for systems from center stacks to instrument panels, from headlamps to head-up displays.

Electronically controlled lenses come standard with each ProMetric I system, allowing manufacturers to use software to easily set focus and aperture settings on the fly as image distance changes, or when required for regulatory testing (such as DFF Black Mura Gradient measurement).

Lighting
From individual LEDs to large luminaires, Radiant’s light measurement expertise spans decades with applications in data acquisition for light source modeling to correction of non-uniformity for large LED panels. The ProMetric I is applied for both goniometric and non-goniometric measurement of light sources, completely characterizing the three-dimensional output of a source (generating ray sets, IES, or LDT/EULUMDAT files) or evaluating illuminance, luminous intensity, and chromaticity as well as geometric aspects like distribution cut-off gradient and shape.
