DMS 201 Manual goniometer for display measurement

Loading Loading

Low-cost solution, simple and easily extended

The DMS 201 is a low-cost goniometer with 2 or 3 manual axes for analysis of the electro-optical properties of displays. The measuring system incorporates a manual positioning device and is used for determining luminance, contrast and color behavior subject to variable electrical control and different viewing angles.

Additionally, measurements with reflective and transmissive test illumination are possible. The DMS 201 is suitable for all applications in which automatic angle scans are not required.
