Radiant Vision Systems has released a 43MP CCD imaging system as part of its line of ProMetric imaging photometers. The new ProMetric Y43 Imaging Photometer provides extremely high CCD resolution to enable advanced measurement capability for display and consumer electronics manufacturers. It complements the Y2, Y16, and Y29 models of Radiant’s ProMetric Y series of imaging systems, with superior imaging resolution for measuring high-definition displays at the pixel level, or for imaging electronic components and surfaces in maximum detail using a single camera.
The high spatial resolution of the Y43 allows the camera to detect pixel and sub-pixel luminance and color variations across display bright states (gray levels), subtle surface anomalies or particles, and other defects that are easily missed by human visual inspection or competitive measurement systems. Defects in images can be identified and quantified using Radiant’s TrueTest Automated Visual Inspection Software (available with tests for comprehensive display defect detection, mura identification & assessment, or application-specific testing of automotive displays, head-up displays, and augmented or virtual reality displays). TrueTest applies objective analysis and repeatable pass/fail criteria to Y-series images for fully automated quality control.
OLED, microLED, quantum dot, and other display technologies rely on increasingly small light-emitting elements for greater visual detail and control of display brightness, color, and contrast. As display pixels and sub-pixels shrink in size, the demand for higher-resolution measurement systems to test display visual performance at every variable element is greatly increased.
Engineering teams at Radiant continue to pursue of the next evolution in resolution for imaging photometers. The company has been dedicating significant time and research to ensure that it is able to achieve high-resolution imaging while maintaining the signal-to-noise advantages that Radiant measurement systems are known for. Working directly with CCD vendors, Radiant seeks resolution improvements only if they do not sacrifice image quality and measurement capability. The ProMetric Y43 imaging system is the result of this commitment, providing manufacturers with a metrology solution that maximizes measurement quality at 43 megapixels.
The ProMetric Y-Series imaging systems are engineered with scientific-grade, cooled interline CCD sensors that limit image noise for highly accurate, repeatable imaging. The new ProMetric Y43 uses a 43-megapixel (8040 x 5360) CCD sensor with low image noise for repeatability inspecting small visual details. Time to measure a complete high-resolution display at several CCD pixels per display pixel is less than 1.5 seconds, enabling production-level applications such as in-line quality control.
The ProMetric Y imaging systems are available with an internal Tristimulus Y filter for photometric metrology applications (light and color measurement), or as a radiometric imager for radiant intensity measurements (for imaging surfaces and non-lit components, or measuring near-infrared light). All Radiant ProMetric imaging systems are designed to simulate human perception of brightness and color. The Y-series camera systems combine the benefits of automation—speed, repeatability, and objective data—with the sensitivity of human vision to ensure that quality assessment of light and display products accurately reflects the human user’s experience.
Each Y-series model is available with a variety of interchangeable lenses calibrated at each F-stop, enabling optimized measurements over a wide range of working distances and viewing angles. ProMetric Y supports high-speed USB and Ethernet communications, with reliable operation over long distances. Smart Technology features, including electronic focus and aperture control, simplify setup via software, reduce measurement time, and improve accuracy. A ProMetric Y imaging photometer combined with Radiant TrueTest Software provides a complete, turnkey solution for testing a variety of displays, keyboards, illuminated components, cover glass, and device surfaces.
