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.
In today’s automobiles, versatile high-resolution touchpads have replaced analog gauges and knobs. Modern smart lighting adjusts to changing conditions. Radios have been replaced with multi-function, touch-sensitive infotainment displays. Generic sealed-beam and capsule headlamps have been superseded by stylish, aerodynamically-efficient, model-specific LED and HID headlamp assemblies. Head-up displays (HUDs) are becoming an automotive standard.
Early Model-T Ford vehicles didn’t even have a speedometer (their top speed was just 35 mph), but soon after, dashboards began to include multiple gages, indicators, and vehicle controls. (Fun fact: the word ‘dashboard’ originates from horse-drawn wagons and carriages, where a board at the front protected passengers from mud that was ‘dashed’ up by the horses’ hooves.)
From wearables to embedded displays, developments in display technology have increased the need to evaluate the visual quality of light from every view angle. To ensure that brightness and color remain consistent across LCD and OLED displays, even when embedded into assemblies or viewed at variable angles, manufacturers are seeking automated systems to control view performance from design to production.
A conoscope lens measures the angular distribution of color, luminance (brightness), and contrast from displays and display components. Radiant's conoscope lens captures a full cone of view angle data in a single measurement to ±70 degrees. You get quick, accurate results, making the system ideal for both R&D projects and in-line production quality control.
The conoscope lens mounts directly to ProMetric® imaging photometers and colorimeters, providing a seamless solution for measuring the angular distribution of color, luminance (brightness), and contrast from displays and display components, capturing multiple view angles in a single measurement.
The FPD Conoscope Lens system from Radiant utilizes Fourier optics to capture a full cone of photopic and colorimetric data in a single measurement to ±70 degrees, giving you extremely fast, accurate results ideal for labs or in-line quality control. Learn more about the FPD Conoscope Lens view angle measurement solution in this presentation.
The most important part of any camera is the lens, which directs light in ways that create images to mirror reality. Today’s photographic lenses are sophisticated instruments composed of multiple elements (individual glass or plastic lens discs), paired with an aperture, shutter, and controls, all arranged along a central axis, and held within the lens casing.
Display quality has never been more valued than it is today—and not just because we want the ultimate HDTV experience or the prestige that comes with owning the latest O
Radiant technologies are thoughtfully engineered to achieve the fastest, simplest, and most accurate measurements of light, color, and surfaces. Imaging colorimeters and photometers leverage scientific-grade CCDs, high resolution, low noise, and factory calibration to ensure consistency of data across R&D to production. Utilizing photopic filters, Radiant cameras acquire absolute luminance and color information to qualify devices against human visual perception.
