Thermal Imaging Microscope for Temperature Analysis
True Temperature Mapping
When imaging small devices comprised of different materials, much of the contrast on the image is usually due to emissivity variations, not to temperature variations. Measuring true temperature with the Micro infrared microscope requires compensating for these emissivity variations according to the following procedure.
First, the unpowered device is placed on the thermal stage so that its temperature can be precisely controlled. After it has reached a stable temperature, the Emissivity Tables software tool is used to automatically create an emissivity map of the device. By applying the emissivity map to thermal images, accurate temperatures can be obtained at any point on a device.
