Used for precise measurement of qualities of light across a display, the ProMetric Y Imaging Photometer objectively quantifies spatial luminance, contrast, and uniformity values in addition to defects like mura, light leakage, dead pixels, lines, and particles.
With extremely high-resolution sensor options, the ProMetric Y is ideal for capturing measurements at the pixel and subpixel for light output characterization. In emissive displays like microLED, mini LED, and OLED, independently emitting pixels can vary from one to the next, causing non-uniformity in brightness or color that can worsen at different display bright states. Within a single measurement, the ProMetric Y measures an entire display in exact detail across thousands of emissive pixels, acquiring values for each pixel in the display.
The ProMetric Y paired with TrueTest™ Software automatically applies analysis regions to unique symbols (whether alphanumeric or other shapes). Thresholds can be applied for target luminance values that allow discrete measurement of symbol sets. Evaluate symbol brightness, inter- and intra-character uniformity, and light leakage or reflections from symbols on adjacent surfaces.
Cosmetic Surface Defects
Applying photometric evaluation of subtle fluctuations of light, the ProMetric Y can be utilized for automated visual inspection of surfaces where reflections and contrast variations indicate defects. Using high resolution and dynamic range, the ProMetric Y can classify extremely subtle scratches, dents, missing or distorted elements, debris & particles, smudges, and overall surface uniformity, applying tolerances for acceptable defect type and severity.
