VDU Display Testing

2D SPECTRAL IMAGING COLORIMETERS FOR DISPLAY TECHNOLOGIES

The VDU™ Series combines the strengths of a 2D CCD image sensor with a high-performance spectroradiometer (optional) and CIE XYZ filters.

UNWAVERING PRECISION & CONSISTENCY

Essential for quality assurance in display technology, the VDU™ Series characterizes display products by measuring their color, luminance, and uniformity, ensuring top-tier performance across various applications. Integrating an RGB camera with our state-of-the-art spectroradiometer delivers both accuracy and flexibility for laboratory measurements and the speed and durability of demanding production environments.

  • User-programmable regions of interest
  • Measures luminance, CIE chromaticity, CCT, dominant and peak wavelength, spectral power distribution (SPD), and uniformity
  • Optional integrated spectroradiometer significantly improving accuracy, repeatability, and unit-to-unit consistency
  • NIST traceable, original system calibration is performed in our world-class ISO/IEC 17025 accredited laboratory by NVLAP

VDU-12

The VDU 12 is a next-generation family of 2D spectral imaging colorimeters that includes a 2D CCD image sensor, CIE matching filters, and a high-performance spectroradiometer (optional) for performance optimization. This results in a rapid and highly accurate system for display measurements, including luminance, correlated color temperature (CCT), CIE chromaticity, and uniformity.
