ProMetric® I151 Imaging Colorimeter
The world’s fastest and most accurate high-resolution imaging colorimeters
The ProMetric® I151 delivers our highest resolution and measurement precision to support the performance and throughput requirements of high-volume manufacturing lines for augmented and virtual reality displays and components. Offering a 151-megapixel (14192 x 10640) image sensor, the resolution of the system enables pixel-level measurement of displays used in AR and VR devices (LCD, OLED, microLED, and others).
- High-speed, high-resolution image sensor
- Replicates human visual perception in AR, VR, and MR headsets
- ARVR Lens with a field of view up to ±60° (120° total) circular
- Seamless integration with TT-ARVR™ Software for comprehensive in-headset testing
Enables Precise Quality Control of Near-Eye Displays in AR/VR Devices
The ProMetric I151® imaging colorimeter is paired with the AR/VR lens with a compact design for positioning the camera entrance pupil at the human eye position. Displays viewed near the eye, such as those in AR/VR devices, create immersive virtual experiences. However, as display images are magnified to fill a user’s field of view (FOV), display defects are also magnified. Issues with uniformity of brightness and color, dead pixels, line defects, cloudiness, and image position become more evident to the user whose eyes are only centimeters away from display screens. In these cases, display quality testing is a critical step for product quality control. Test and measurement solutions for evaluation of NED quality include photometric imaging systems paired with software for luminance and chromaticity measurement and analysis. However, traditional optical components that measure displays like televisions and smartphones did not include design considerations for replicating the human eye’s view of visual input at the distances required for head-mounted display devices.
When paired with the AR/VR lens, the I151 delivers a compact design for positioning the camera entrance pupil at the human eye position, featuring a circular field of view (FOV) of 120 degrees. This integrated solution captures color and luminance measurements that match human visual perception, enabling precise quality control of near-eye displays in AR/VR devices.
