High-Speed High-Sensitivity SWIR Cameras
High-speed high-sensitivity SWIR cameras combine fast dynamic acquisition with low-light detection capability, enabling the capture of transient weak infrared signals. They are widely used in high-speed dynamic testing scenarios such as semiconductor photovoltaic inline inspection, pulsed laser spot monitoring, and plasma/combustion transient observation.
