High-precision electro-optical characterization of displays

In 2012, Instrument Systems GmbH acquired the development and production rights of Autronic-Melchers GmbH for its display measurement systems.
The instruments are based on goniometric measurement methods, and they have defined worldwide standards for determining the viewing-direction dependent characteristics of displays.

All measurement systems can be universally applied for any display technologies (LCD, AMOLEDs, e-Paper, etc.):

A comprehensive range of accessories, e.g. illumination devices and forced-air temperature-control chambers, is supplied for all measurement systems.

Goniometric measurement systems

The goniometers of the DMS Series provide an optimum system solution for the detailed analysis of the electro-optical characteristics of displays as a function of viewing angle in quality assurance, as well as research and development. The following measurement systems are supplied:
