FPD Conoscope Lens
Click to Enlarge Thumbnails
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 evaluate a wide range of FPD types including those based on LCD, OLED, and backlight technologies.
