Viewing-angle measurements of flat panel displays

The CONOMETER® 80 is the ideal instrument for measuring luminance, contrast, and gamma of emissive displays as a function of viewing angle.

The simple design contains fewer optical elements and therefore comes at a much lower cost than competitive conoscopic (Fourier) lens systems. The system is able to measure displays as small as 6 mm wide. With the ability to capture a wide luminance range (0.01 to more than 100,000 cd/m²), the CONOMETER® is ideally suited to measure viewing angle characteristics of backlights, black levels, edge-lit displays and much more.
