I. High-Sensitivity and High-Speed sCMOS Cameras
sCMOS scientific-grade cameras, with ultra-low readout noise, ultra-high quantum efficiency, wide dynamic range, and high-speed imaging capability, have become key imaging devices for extremely weak optical signal detection. They are now widely used in cold atom physics experiments, quantum research, plasma transient process diagnostics, super-resolution microscopy, magnetic domain microscopy, semiconductor wafer micro-defect inspection, Raman spectroscopy, and other low-light scenarios. Their industry application value and demand continue to grow.
