Our SWIR Camera can be employed in inspecting semiconductors such as silicon bulk ingots, and sliced wafers. SWIR resembles obvious mild in that photons are mirrored or absorbed by an item, making the solid contrast wanted for high-resolution imaging. Starlight and track record radiation (nightglow) are pure sources of SWIR https://www.mindvision.ltd/Special-Camera/Short-wave-Infrared-Camera.html
