CSEM and QDI Systems Unveil Quantum Dot CMOS Image Sensor for Direct X-Ray and SWIR Imaging

Swiss technology innovation center CSEM, in collaboration with Dutch deep-tech startup QDI Systems, has developed the world’s first image sensor to directly convert X-rays into electronic signals using quantum dots (QDs) on a CMOS platform. This revolutionary approach enables compact, low-cost, and scalable wide-spectrum imaging—from X-rays through visible to short-wave infrared (SWIR)—with applications ranging from safer medical diagnostics to advanced industrial inspection and intelligent recycling.
