Small device elements such as microdisplays and nano-scale light sources such as OLED, microOLED, and microLED pixels require specially designed lens options for accurate inspection. 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. Available with 5X and 10X magnification, the microscope Lens provides a compact and efficient photometric measurement solution for controlling the visual quality of displays and other devices.
