High-Speed InGaAs SWIR Line-Scan Camera
LiSa SWIR Linescan Camera
LiSa is a high-speed InGaAs SWIR line-scan camera for continuous machine-vision inspection of moving materials. Its 2048 × 1 sensor, greater than 110 kHz full-resolution line rate, external triggering and Camera Link interface support semiconductor, photovoltaic, food, recycling, web and process-control applications.
LiSa Linescan SWIR Camera
Product Overview
Continuous SWIR Imaging at Production-Line Speeds
Unlike an area-scan camera, LiSa records one line of SWIR pixels at a time. As a conveyor, web, wafer or scanning stage moves the target, successive lines are assembled into a continuous 2-D image. This architecture is ideal for materials already moving through an industrial process.
The InGaAs detector operates across the standard SWIR region, where silicon, moisture, polymers, coatings and organic materials can show contrast that is weak or invisible to conventional visible cameras.
