RADIANT VISION MICROSCOPE LENS IMAGING PHOTOMETER

Image magnification solution for extremely high-resolution light and display testing

Radiant Vision Systems Microscope Lens developed with high-resolution imaging of extremely small components and features, such as individual LEDs, display pixels, and subpixels. Provides 5X and 10X magnification, capturing a greater number of CCD pixels per display pixel or component feature for fine-detail measurement. The lens mounts directly to a Radiant ProMetric® Imaging Colorimeter or Photometer, and features ProMetric or TrueTest™ Software for intuitive system setup and configurable automated measurement sequences. Supported extensive data analysis and display functions including
isometric plots, cross-sectional graphs, radar plots, and bitmaps.

The Radiant Microscope Lens can be used to evaluate properties of LEDs alone or in an array, including:

  • LED uniformity
  • LED edge contrast (uniformity falloff)
  • Effect of cross-talk between LEDs (undesired illumination of an LED by a neighboring LED on an array or panel)
  • Cross-section plots showing LED luminance uniformity

The Microscope Lens can easily be removed and replaced with standard lenses for additional measurement applications, including measurements that require the full display field of view, such as uniformity of luminance and chromaticity, contrast, mura, and other features. Learn more
