Introduction
Radiant Vision Systems has recently announced the release of a new 20x microscope lens designed for testing small components such as individual LEDs, Micro LEDs, and Micro OLEDs, as well as display pixels and subpixels.
Product Features
This lens can be directly mounted onto Radiant’s ProMetric® imaging colorimeters or luminance meters, equipped with ProMetric or TrueTest™ software, providing intuitive system setup and configurable automated testing sequences.
Measurement Capabilities
The high magnification of the 20x microscope lens allows imaging colorimeters or luminance meters to focus on a greater number of image sensor pixels for each display pixel, simplifying the measurement tasks for small displays.
Industry Challenges
For years, the display industry has focused on producing screens with ever-increasing resolution. This includes the use of LEDs, where each pixel of the display emits light independently, as well as the transition to Micro LEDs and Micro OLEDs. As display resolutions increase, pixel sizes become smaller and densities higher, presenting significant challenges for manufacturers in terms of inspection.
Expert Insight
“Due to the shrinking size and increasing number of pixels in individual small displays, measuring the quality of self-emissive displays at the pixel and subpixel level has become a tricky challenge,” said Eric Eisenberg, Development Manager of Optical Components at Radiant Vision Systems. “For instance, we are seeing micro-displays for AR/VR devices containing thousands of pixels per inch, which requires measurement solutions to provide high-resolution imaging for extremely small features.”
Enhanced Precision
With the introduction of the new 20x microscope lens, featuring ultra-high quality objectives that achieve near-diffraction-limited spatial resolution performance, we can capture more precise pixel details and enhance the consistency of accurate measurements. The correction factors provided in this solution are used to adjust each display, evaluating visual quality from the user’s perspective when viewing AR/VR devices.
Measurement Accuracy
Radiant’s microscope lens can magnify the detailed features of display sensors while utilizing multiple sensor pixels on a high-resolution (61-megapixel) image sensor to capture display pixels and subpixels, improving measurement accuracy. This combination of high value, high performance, and high flexibility offers manufacturers an easy-to-use measurement control solution that optimizes testing efficiency and supports advanced analysis.
Compatibility
The 20x microscope lens can be used in conjunction with the ProMetric Y Series imaging luminance meters for measuring luminance only or with the ProMetric I Series imaging colorimeters for simultaneous measurement of luminance and chromaticity values.
