OL 770-DMS Display Measurement System

Features and Benefits Specifications Information Request



The Optronic Laboratories OL 770-DMS Display Measurement System is the most versatile system available today for manufacturers developing new displays. Capable of performing all critical measurements, it provides a complete solution for modern display measurement requirements. Developed to meet the needs of R&D, production, and quality assurance, the OL 770-DMS’s unique design features, high sensitivity, and powerful, adaptable software make it ideal for performing measurements on ALL display types.

The OL 770-DMS is comprised of the OL 770 Multichannel Spectroradiometer, the OL 610 CCD Imaging Telescope, and intuitive Application Software. The state-of-the-art high-speed, multi-channel spectroradiometer is capable of performing display measurements rapidly and easily. Accurate measurement of color, luminance, and spectral radiance is obtained almost instantly at the click of a button. Incorporating an innovative concept, the OL 610 couples a CCD camera with direct viewing optics for precise viewing of the measurement target area. The CCD camera allows for remote viewing in locations that might otherwise be inaccessible. Polarization errors are insignificant compared to other measurement systems, resulting in accurate measurements of LCD and AMLCD displays, for example. An automated three axis positioning stage is also available, which enables the system operator to control the measurement area of the display from a remote location for a completely hands-off operation. The OL 770-DMS’s modular concept does not require an additional system when another measurement requirement arises, but simply the addition of the appropriate accessory.

When operating in auto-exposure mode, the measurement time is optimized to increase the signal-to-noise ratio by selecting integration times based on the available light level. The outstanding sensitivity, which results in incomparable measurement times and accuracy, places it in a class all by itself. The system can be configured for display contrast measurements. Also, Optronic Laboratories manufactures diffuse and specular standards, illumination sources for characterizing display reflectance, and NIST-traceable calibration standards.

The user-friendly software allows the operator to easily transfer results and graphs to customized reports or spreadsheets. Real-time images of the measurement area that are obtained via an on-board CCD camera are displayed and may be stored with each set of measurement data. Calibration routines are also included with the OL 770-DMS software and are as simple as performing a measurement. Unlike other manufacturers, all Optronic Laboratories measurement software includes calibration routines at no additional cost. An optional software development kit is available for custom programming and system integration.

The OL 770-DMS is capable of many types of measurements, including

  • Luminance
  • Diffuse Reflection
  • Chromaticity
  • Gray Scale
  • Specular Reflection
  • Contrast Ratio
  • Gamma
  • Sunlight Readability
  • Uniformity
  • Viewing Angle
  • Ambient Contrast Ratio



The OL 770-DMS Display Measurement System offers a complete solution for display measurement requirements.
