You’re in the driver’s seat of your car, glancing at the map on your GPS display to navigate the journey. Meanwhile, your spouse is in the passenger seat, using a display interface in the center console to adjust the temperature and air flow inside the car for everyone’s comfort. And your kids are strapped in the back seat, heads bent together over a shared tablet that’s playing the latest Pixar video release to keep them entertained on the drive.

On an aircraft, critical safety and operational information is relayed to pilots and passengers primarily via artificial light.
The Auto-POI (Automatic Points of Interest) functionality available in Radiant's TrueTest™ software platform enables the automatic application of points of interest on backlit symbols using luminance values and chromaticity coordinates to define measurement thresholds. Learn how to use this tool for quick and efficient measurement of various symbol sets in a backlit panel, button, sign, or instrument cluster.
Learn a unique application of Radiant ProMetric® imaging solutions for measuring OLED displays on the pixel and sub-pixel level to calculate non-uniformity and coefficients for pixel-level luminance correction. This process, referred to as “demura,” adjusts the luminance and/or chromaticity of each OLED pixel to produce displays with an entirely uniform appearance.
In this article, we discuss unique measurement considerations for ensuring the quality of LED sources, and equipment for measuring LED displays, individual sources, and luminaires.
In this 50-minute webinar, International Senior Business Advisor for Radiant Automotive applications Matt Scholz presents a method for repeatable sparkle measurement across users, devices, and systems, with quantifiable results that correlate to human visual perception of display quality.
In this article, we describe a method for the measurement of large light sources in a limited space that efficiently overcomes the physical limitations of traditional far-field measurement techniques. The measurement is performed from within the near-field of the light source, enabling a compact measurement set-up, and generates a detailed near-field color and luminance distribution model that can be directly converted to ray sets for optical design and that can be extrapolated to far-field
For optical design and product qualification, the output color and luminance distributions of large light sources are needed to qualify and predict the performance of architectural, automotive, street, security, entertainment and other lighting systems. However, these distributions are difficult to measure because of both the size of the source and the large space required for the measurement.
In this article, we discuss the manufacturing challenges that are common in OLED displays, and correction methods that can be used to adjust the output of individual pixels of emissive displays (like OLED, microLED, and others) to ensure uniformity of brightness and color, preventing waste of "defective" materials and improving manufacturing efficiency.

On a passenger airliner, backlit displays such as exit signs, fasten seatbelt signs, lavatory signs, and other signage are crucial for both comfort and safety. These products must meet strict tolerances for brightness and color—as defined by each aircraft manufacturer—as well as stringent industry regulations.
With absolute quality as a focus, Luminator Aerospace performs extensive light and color measurement tests on products such as exit signs, fasten seatbelt signs, lavatory signs, and other signage. These tests ensure that customer specifications are met to exact values and that a record of verifiable quality data is documented for each part.
In this article, learn how photometric and colorimetric technology matches the visual sensitivity of human vision. We discuss the advantages and applications of CCD imaging for light and color measurement, as well as component and surface inspection, that most accurately reflects the human visual experience.
This paper describes precise geometric, optical, and software parameters of a sparkle measurement method, which has been proven to match human visual perception of display quality with repeatable results. Using this method, OEMs and manufacturers of displays can define precise, measurable tolerances for sparkle and establish standard quality control processes for anti-glare displays.
The Microscope Lens mounts to any ProMetric® Imaging Coloriemter or Photometer to enable high-resolution imaging of extremely small components and features, such as individual LEDs and display pixels. Provides 5X and 10X magnification, capturing a greater number of CCD pixelsper display pixel or component feature for fine-detail measurement.This Spec Sheet features:ApplicationsBenefitsKey FeaturesSpecifications
These days we’re even more reliant on our screens than Snow White’s queen was on her magic mirror. Considering their importance, the need for quality and clarity in displays—from televisions and smart phones to automobile dashboards to VR headsets—is no fairy tale. Mura is a Japanese word that means unevenness, irregularity, or blemish.
The Near-Infrared (NIR) Intensity Lens system is an integrated camera/lens solution that measures the angular distribution and radiant intensity of 940 nm near-infrared (NIR or near-IR) emitters. The NIR Intensity Lens system utilizes Fourier optics to capture a full cone of data in a single measurement to ±70 degrees, giving you extremely fast, accurate results ideal for in-line quality control.

Measurement techniques for NIR LEDs and lasers ensure the performance of Time-of-Flight (ToF) light-based proximity sensing and 3D sensing using dot patterns produced by diffractive optical elements (DOE). To ensure performance, accuracy, and safety of devices and systems that use NIR sensing, an effective test and measurement solution is needed.
The properties of light that stimulate the eye and build our visual perception—when thoughtfully designed into lighted devices—can create unrivalled visual experiences. Thanks to well-established scientific methods, we can quantify the human eye's response to light in a mathematical context for use in optical metrology.
