Single-Photon Avalanche Diode (SPAD) sensors bring unmatched speed, sensitivity, and precision to photon detection—capturing even the faintest signals of light. By integrating advanced on-chip processing, these compact and scalable solutions simplify system design while delivering high-performance imaging for scientific, industrial, and emerging applications. From SPAD chips to full camera systems, single-photon technology is redefining what’s possible in low-light imaging and measurement.
