Fast, Accurate, Low-cost View Angle Performance Measurement Solution for Displays
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 a CCD so that each pixel corresponds to a different emission angle. The 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 and OLED technologies as well as backlights.
