Measures more — and faster
The CONOMETER® 80 measures display viewing angles over a wide range of luminance — from black levels to the brightest backlights. Measurements of 100 cd/m2 or more can be completed in less than one second, and low light level measurements down to 0.013 cd/m2 can be completed in just ten seconds. The CONOMETER 80 is truly in a class by itself.Simplicity
While measuring viewing angle performance with heavy, Fourier lens systems requires 6-axes stages or robots to achieve sample alignment, the CONOMETER 80 alignment procedure is straightforward and assured. Weighing only 0.5 kg, the CONOMETER 80 readily integrates into any test scenario. When placed directly at the display surface, the lens hood sets the optical axis for measurement, and shields the test from external stray light. Tip and tilt adjustments are not required — rotation and translation remain for complete alignment.
Analysis
Using the included Photometrica software, users can quickly apply tools such as profiles to evaluate display performance. In addition, various measurement layers at different display settings are acquired in the same document to enable more complex display evaluations such as contrast, gamma, and inversion.

Customization and Automation
With the software development kit (SDK), scripting within Photometrica is available to simplify the user interface, streamline repetitive tasks, or integrate with external devices such as video pattern generators. For full automation, users may create applications using SOAP (LabVIEW, MATLAB, etc.), or COM (C#, C++, VB) interfaces.
Available with or without a fixed lens hood
The Conometer 80A features a removable lens hood whereas the Conometer 80B has a fixed lens hood. Both models have the same overall dimensions.
Need Color?
If luminance and color viewing angle measurements are required, then the Conometer Viewing Angle Lens with an imaging colorimeter from WP is the solution. The Conometer lens offers Fourier imaging out to ± 80˚.
