| Whether in vehicle laboratories or display and wafer production, precise optical metrology is key to ensuring quality and efficiency.
In this issue, we present two highlights from Instrument Systems:
our new stand-alone screen photometer for headlamp testing, and the LumiTop series for fast and accurate MicroLED and MicroOLED measurements.
We also invite you to join us at the MicroLED Forum 2025 in Taipei, where our expert Dr. Thomas Attenberger will share the latest insights into traceable color measurement for MicroLED applications.
Any questions? Please don't hesitate to contact us!

|
| | | | | | Traceable and Accurate Color Measurement at MicroLED Wafers | |
|
| Presenter: Dr. Thomas Attenberger
Date: 2025/11/12
Location: Taipei, Taiwan
MicroLEDs are making their way into many applications in high-quality displays. Testing at an early stage helps manufacturers ensure best performance in color and luminance homogeneity right from the start of production. Instrument Systems has developed a high-end test camera dedicated to highest photometric and colorimetric test accuracy even for the smallest MicroLEDs. The camera is referenced to a high-accuracy spectrometer of the CAS 140D series, which guarantees traceability to international standards. Special calibration algorithms have been developed to take spectral variations of the individual emitters into account and ensure accurate, reproducible results. In combination with an optical excitation system, complete MicroLED wafers can be analyzed in color and luminance within minutes. In this presentation, we will share first results that demonstrate how this approach helps manufacturers achieve reliable quality and efficiency in MicroLED production.
