The top five infrared manufacturers accounted for around 90% of total global shipments in 2025, according to Thermal Imaging and Sensing 2026, a report by market research and strategy consulting firm Yole Group. Among them, Raytron ranked first with a 30% share, maintaining its global leadership for the second consecutive year.
Raytron attributed the position to continued investment in technological innovation spanning infrared detector development, advanced packaging and AI algorithms. The company has advanced infrared detector miniaturization and resolution through successive reductions in pixel pitch, from 35 μm to 17 μm, 12 μm and 8 μm. Raytron developed its 8 μm infrared detector in 2021 and achieved mass production in 2025. Smaller pixel pitches allow more pixels to be integrated into the same detector area, improving spatial resolution, and can also enable smaller detectors and lower system costs at the same resolution.
On packaging, Raytron introduced SWLP (Super Wafer Level Packaging), featuring a dual-layer structure designed to improve detector protection and reduce reliance on specialized cleanroom environments during downstream integration. At CIOE 2026, the company introduced BCoS (Bump Chip on Substrate) packaging technology, which eliminates wire bonding and simplifies the packaging structure compared with traditional WLP solutions. For products with equivalent specifications, Raytron said BCoS reduces detector thickness by approximately 21% and footprint by nearly 40%.
Raytron also unveiled its Infrared Vision-Language Model at CIOE 2026. Trained on a proprietary multimodal infrared dataset comprising over 5 million data samples, the model has achieved on-device deployment and is being applied to intelligent analytics in areas such as industrial temperature measurement, gas detection and night vision security.
