Microscope Lens Solution
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 any ProMetric® Imaging Colorimeter or Photometer, at resolutions from 2 to 43 megapixels. Utilized 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. 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 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, and prevents waste due to poorly-performing (but correctable) components.

• Accurate, reliable measurement of display luminance and chromaticity
• 5X microscope and add-on 2X teleconverter (converts 5X to 10X lens)
• Imaging for multiple data points, increasing measurement efficiency
• Magnification of details captured by high-resolution image sensors (to 43 megapixels)
• Combination of value, high performance, and flexibility, designed for R&D and quality assurance
• Easy-to-use measurement control and analysis software
  

The Microscope Lens is ideal for capturing small details in extremely high resolution. The camera/lens solution offers photometric imaging efficiency to address both off-line and in-line applications:

• High-resolution imaging of extremely small components and component features
• Evaluation of display pixels and pixel structures (including subpixel level)
• Evaluation of individual LEDs, including microLEDs
• Characterization for display design and R&D
• Production measurement for quality control at end-of-line
