Display objective lens FPD

high-resolutionconoscope

The Radiant Vision Systems FPD (flat panel display) Conoscope Lens enables high-resolution photopic measurement of the angular distribution of color, luminance, and contrast for displays and display components. Radiant uses Fourier optics that map an emitting spot to an image sensor so that each pixel corresponds to a different emission angle. The FPD Conoscope Lens captures a full cone of view angle data in a single measurement to ±70 degrees. This provides quick, accurate results, making the system ideal for both R&D projects and in-line production quality control. The lens is well-suited to a wide range of FPD types including those based on LCD, OLED, and backlight technologies. The FPD Conoscope Lens provides an angular resolution of 0.05 degrees per sensor pixel. Paired with a ProMetric® I Colorimeter or Y Photometer, the Conoscope Lens has the capability to measure luminance, radiance, angular contrast, CIE chromaticity coordinates, and correlated color temperature (CCT) with a high degree of accuracy at each view angle. The FPD Conoscope Lens simultaneously acquires view angle measurements to ±70 degrees. Designed to mount directly to a ProMetric camera, the lens and camera combination can be purchased for a fraction of the cost of alternative solutions, and offer reduced hardware size and complexity compared to typical goniometric measurement systems for R&D applications. Because of its speed and compact form factor, the FPD Conoscope Lens solution is also ideally suited for in-line inspection of displays during production.
