INFRASCOPE III

QFI’s InfraScope is the only infrared thermal microscope with automatic emissivity correction. Emissivity is the material property that governs how strongly a material will emit infrared radiation at any temperature. Some materials, like metals, emit very little infrared compared to bulk semiconductor. The infrared image at right is not powered, and every material is at the same temperature. All of the image contrast is due to material emissivity differences. These emissivity differences can mask shorts, making them impossible to detect. For example a very hot spot covered by a metal may emit very little, whereas another area, only incidentally heated but with high emissivity may emit prodigiously. The FA worker will erroneously believe the short is at the high emissivity area. The InfraScope is the only infrared microscope with algorithms that automatically correct emissivity in real time at each pixel to give true temperature images. No simple algorithms find hot spots so effectively.
