Core offering

ISDI designs and manufactures high-performance wafer-scale CMOS image sensors and CMOS X-ray detectors for the detection of X-rays, visible light, electrons, and protons, serving medical imaging, industrial non-destructive testing, and scientific applications. Through its Spectrum Logic subsidiary, ISDI offers a range of standard detectors, and the company also provides a complete custom image sensor design service for small-to-medium volume production where standard commercial sensors are unavailable or uneconomical.

Product overview

ISDI (Image Sensor Design and Innovation) is an innovator in high-performance X-ray detectors and CMOS image sensors. The company operates through its core product lines: standard CMOS image sensors (including wafer-scale sensors and line-scan arrays), and its Spectrum Logic subsidiary which manufactures CMOS X-ray detectors for medical, industrial, and scientific applications. ISDI also offers comprehensive custom image sensor design services for specialized applications where standard products cannot meet requirements. The product portfolio spans from individual sensor chips (Cerberus, TY-1107, IS-1512) to large tiled detector arrays (IS-3131 at 309×307mm²), and includes application-specific products like the BergKristall Contact Image Sensor and SE1K128 NIR sensor for glucose monitoring. Recent recognition includes the King's Award for Enterprise Innovation 2024 for the 2824HS/2824HR detectors used in EV battery inspection.
