Request InfoRadiant Vision Systems, Test & MeasurementThe Radiant Vision Systems conoscope lens enables high-resolution photopic measurement of the angular distribution of color, luminance, and contrast of displays and display components. Fourier optics map a light-emitting spot on a display to the connected camera’s CCD so that each pixel corresponds to a different emission angle. This enables the conoscope lens to capture a full cone of viewing angle data in a single measurement to ±60 degrees for quick, accurate results. The conoscope lens features an angular resolution of 0.06 degrees per CCD pixel. Paired with the 16-megapixel...See full productRelated content from Photonics MediaPRODUCTSVision Spectra Autumn 2022 IssueColor Inspection SystemThe ACIS™ Area Color Inspection System from Radiant Vision Systems LLC provides color and quality inspection of characters and symbols.
