An apparatus that can be used to gauge the angular distribution of a light source is a conoscopic lens. When compared to a lens, as in photography, its use is very different. A conoscopic lens produces images that resemble those of fisheye lenses. That picture is incredibly distorted. A conoscope is a device used to gauge how light is distributed angularly.
Comparable to camera lenses, normal lenses don’t measure the spatial (position) distribution of light. A typical lens would produce a photo of an artwork that is strikingly similar to the original. But if they use a conoscope to photograph a painting, they will obtain a picture that resembles one made with a fisheye lens.
The Global Conoscope Lens market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
The availability of a new Conoscope lens for Radiant Vision Systems ProMetric® imaging photometers and colorimeters has been announced by Radiant Vision Systems, a leading supplier of visual test and inspection systems for lighting and display devices.
Manufacturers of flat panel displays (FPDs) can quickly and precisely assess the viewing angle performance of displays in real-time because the Conoscope lens simultaneously measures the colour, brightness, and contrast of different angular distributions of light.
With a 3mm diameter inspection point, the Conoscope lens from Radiant Vision Systems mounts directly to the ProMetric Y16 Photometer or ProMetric I16 Colorimeter using a specialised bracket. It gives viewing angle measurements for light and colour.
Each and every camera from Radiant Vision Systems has ProMetric Software, which offers simple camera setup and scalable automated measurement sequences. Numerous data analysis and display features, such as isometric charts, cross-section graphs, radar plots, bitmaps, and CIE colour plots, are also available.
In order to enable manufacturers to assess devices for display viewing angle performance in time with production, Radiant Vision Systems integrates thousands of inspection solutions into production settings across the globe. This company has demonstrated expertise in implementing Conoscope measurement solutions right on the line.
For seamless evaluation of displays throughout the full product lifecycle, from initial characterisation to quality control, Radiant Vision Systems cameras can even be used concurrently in R&D and production scenarios to obtain similar measurements of viewing angle data.
