Our SWIR Camera can be employed in inspecting semiconductors for instance silicon bulk ingots, and sliced wafers. SWIR resembles visible light in that photons are mirrored or absorbed by an object, generating the solid contrast necessary for top-resolution imaging. Starlight and track record radiation (nightglow) are all-natural sources of SWIR https://www.mindvision.ltd/Special-Camera/Short-wave-Infrared-Camera.html
