fpd conoscope

Fast, Precise, Low-In Cost View Angle Performance Measurement Solutions Offer For Display Applications

Radiant Vision Systems FPD Conoscope Lens is built and designed to measure the angular distribution of color, luminance and contrast from displays and display components. The conoscope lens captures a full cone of view angle data in a single measurement to ±70 degrees. This provides quick, accurate results, making FPD Conoscope Lens the system ideal for both R&D projects and in-line production quality control. The lens is well-suited to a wide range of display types including those based on LCD and OLED technologies, as well as backlights.

The FPD Conoscope Lens mounts directly to a Radiant Vision Systems ProMetric® Imaging Photometer or Colorimeterusing a custom bracket.  Mounting the lens directly to a ProMetric imaging photometer or colorimeter offers the most efficient means of measuring view angle performance using a turnkey, compact camera solution that requires minimal setup and integration time, equipment, or expertise. As part of the ProMetric family of imaging colorimeters and photometers, the FPD conoscope lens and ProMetric camera solution also comes with ProMetric Software, a powerful software suite that provides equipment control, data acquisition and image analysis.
