Delivers semiconductor-grade test for next-generation optical interconnects powering scale-up in AI data centers.

NORTH READING, Mass.--(BUSINESS WIRE)-- Teradyne, Inc. (NASDAQ: TER), a leading provider of automated test equipment and advanced robotics, today announced Iris 100, a production-ready optical test platform for microLED devices. Teradyne Iris 100 brings semiconductor-grade optical test to microLED manufacturing, measuring every individual emitter in an array and integrating directly with the Teradyne UltraFLEXplus platform for combined optical and electrical test.

MicroLED technology underpins two of the fastest-moving areas in advanced electronics, augmented reality (AR) microdisplays and optical data interconnects for AI data center architectures. Both depend on devices that contain hundreds of thousands to millions of individual emitters, each of which must be characterized with production-level precision and throughput. Bench-top optical instruments can characterize these devices in the lab, but they cannot deliver the throughput and cost-per-unit economics that volume manufacturing requires.

Teradyne Iris 100 was engineered for high-volume precision manufacturing with its spectrometer and high-resolution camera that measure the spectral response of the array, and per-pixel luminance and uniformity. Advanced test parallelization and image-processing algorithms enable characterization of a full array containing millions of microLEDs with high throughput. Leveraging Teradyne’s widely adopted IG-XL software, Iris 100 detects optical defects such as dead/stuck pixels and cluster defects early in the manufacturing process. Its NIST-traceable calibration workflow enables absolute measurements that correlate lots, wafers, and manufacturing sites.

"MicroLED is shifting from lab to volume production for both AR microdisplays and, increasingly, optical interconnects, which are becoming foundational to how AI data centers scale beyond copper," said Shannon Poulin, president of the Semiconductor Test division at Teradyne. "Both technologies demand per-emitter test at production throughput, and Iris 100 delivers that today on test infrastructure our customers already run at scale."

Teradyne Iris 100 follows the introduction of Teradyne Photon 100 for silicon photonics and co-packaged optics test earlier this year and the acquisition of photonic test specialist Quantifi Photonics in 2025, extending Teradyne’s test capabilities across the full spectrum of emerging optical test requirements. Iris 100 supports wafer and final test, letting manufacturers add microLED test to fleets they already run, with a roadmap to support photodetector test capabilities in the same insertion.

Key Terms

microled technical

MicroLED is a type of display technology that uses tiny, individual light-emitting tiles to create images with bright colors, sharp contrast, and wide viewing angles. Because of their efficiency and high quality, microLED screens can provide clearer and more vibrant visuals, which can enhance the appeal and performance of electronic devices. For investors, advancements in microLED technology may signal potential growth opportunities in the electronics and display markets.

optical interconnects technical

Optical interconnects are systems that use light instead of electrical signals to move data between parts of computers, data centers, or telecom equipment, like replacing copper wires with tiny light pipes. They matter to investors because they can greatly increase speed and capacity while lowering power use and heat, making digital networks faster and cheaper to scale; think of swapping a crowded city road for a high-speed rail line that carries much more traffic efficiently.

spectrometer technical

A spectrometer is a laboratory instrument that measures how materials absorb, emit or scatter light or other electromagnetic waves to reveal their chemical composition and physical properties — like a barcode scanner that reads a substance’s unique optical fingerprint. For investors, spectrometers matter because they are core tools in research, quality control and regulatory testing; their use or availability can affect product safety, development speed, manufacturing costs and a company’s ability to meet regulatory standards.

nist-traceable calibration technical

Calibration described as "NIST-traceable" means an instrument or measurement has been adjusted and documented through an unbroken chain of comparisons back to standards maintained by the U.S. National Institute of Standards and Technology (NIST), including stated measurement uncertainty. It matters to investors because NIST-traceable calibration supports reliable, comparable test results used in product quality, regulatory compliance, manufacturing yield, and clinical measurements—factors that can affect revenue, costs, legal risk and trust in a company's data.
