MEASURES MORE — AND FASTERUsing the latest CMOS imaging technology, the CONOMETER® 80 measures a wide range of luminance; from black levels to the brightest backlights and out to 80 degrees from normal. Measurements down to 0.01 cd/m2 in are com-plete in under 3 seconds. The CONOMETER 80 is truly in a class by itself.

SIMPLICITYWeighing just 450 g, the CONOMETER 80 can be easily integrated into any test scenario. The align-ment procedure is straightforward and assured. When placed directly at the display surface, the lens hood shields the test from stray light and conveniently sets the vertical measurement axis.

ANALYSISUsing Photometrica® software, users may quickly apply tools such as ellipses, polygons and profiles to evaluate display performance. A multiple of viewing angle measurements can be

contained in a single measurement document. Derived data sets such as gamma, contrast and inversion are easily created.

CUSTOMIZATION AND AUTOMATION With the Software Development Kit (SDK) script-ing within Photometrica is available to simplify the user interface, streamline repetitive tasks or integrate with external devices such as video processors. For full automation, users may cre-ate applications using SOAP (LabVIEW, MATLAB, etc.), or COM (C#, C++, VB).

NEED COLOR?If luminance and color viewing angle measure-ments are required, then the WP214 imaging spectral colorimeter from Westboro Photonics is the solution. The WP214 has the same imag-ing features as the CONOMETER 80, but also includes tristimulus filtering and an integrated spectroradiometer — providing the highest mea-surement accuracy in its class.

SYSTEM RECOMMENDATIONS

• 2.0 GHz and 4 cores • 8 GB RAM • Windows 10, 64 bit • USB 3.1 port. (USB 3.1 PCIe card included with system)

MEASUREMENT AREAThe working distance can be varied to accommodate the pixel pitch of different displays. High resolution watches and cell phones can be measured with the lens almost touching the display glass to measure out to +/-80˚ in a 21 mm spot diameter. Laptop and tablet displays can use the integrated lens hood standoff to measure out to +/-80˚ with a 54 mm spot diameter. Large pixeled monitors and televisions can be measured at larger working distances with correspondingly larger spot sizes.
