The PI 640i infrared microscope kit is ideal for engineers who need accurate temperature data on small electronic devices or Micro-Electro-Mechanical Systems (MEMS). The ability to see thermal variations and make measurements on small targets depends on the detector resolution, and the optics focus the heat energy from the device onto the IR camera’s detector elements. This ensures precise and reliable temperature measurements, essential for detailed thermal analysis of miniature components. Many engineers find that temperature measurements made with contact thermocouples on small electronic devices do not correlate with measurements made using a properly equipped infrared camera. This discrepancy is common when the target size is small, as the connection with the thermocouple can act as a thermal bridge, conducting heat away from the target. In such cases, measurements with a non-contact infrared camera are more accurate, as they avoid the heat conduction issues associated with contact methods. As with microscopes that operate in the visible spectrum, choosing the right optic for any application involves a trade-off between the total observable field of view and the smallest target that needs to be observed and measured. The PI 640i microscope objective can detect temperature changes on targets as small as 28 µm within a total field of view of 18.2 mm x 13.8 mm. A high-resolution IR camera with standard wide field of view optics will only deliver accurate measurements of microelectronic targets with the right infrared microscope optics.
