DMS 201 – Cost-effective manual goniometer

The DMS 201 is a cost-effective goniometer for analyzing the electro-optical characteristics of displays. The measurement system is based on a manual positioning device with 2 axes (optionally 3 axes) and is used to determine luminance, contrast, and color properties at variable electrical driving and various viewing angles. The DMS 201 is ideal for applications that do not require automated angular scans.
