Description

The Radiant Vision Systems Microscope Lens enables high-resolution imaging of extremely small components and features, such as individual LEDs, display pixels, and subpixels. The lens attaches directly to a ProMetric® Imaging Colorimeter or Photometer, available in a range of resolutions to meet specific application needs. Used with Radiant ProMetric or TrueTest™ Software, the Microscope Lens provides a compact and efficient photometric measurement solution for controlling the visual quality of displays and other devices. As displays gain resolution and pixel-density, there is an increasing need to measure much smaller light-emitting elements to ensure accuracy of light output, color, and other qualities. This is especially true of emissive displays like OLED, LED, or microLED, where each pixel in a display produces its own luminance and therefore can vary in output from pixel to pixel. These individual variations can cause non-uniformity of the display that is visible even at a distance, especially when viewing the display at high bright states. Once measured, discrepancies in output from pixel to pixel can be calculated and applied as corrections. This normalization of pixel outputs produces a display of entirely uniform appearance. These calibrations can be carried over from design to ensure accurate pixel output for the given substrate or pixel layout of devices in production operations. Subpixel patterns like those shown in the image here can be challenging to characterize without a very high-resolution system and optics capable of microscopic measurement.
