Field of View Diagrams

Sensors may be used at longer distances than the above diagrams show, with a larger measured spot size. The given measured spot size contains 90% of the energy detected by the sensor. We normally recommend the target is at least twice as large as the given measured spot for maximum accuracy. There is no maximum measurement distance in clean air; this is because the PyroMiniUSB detects only the wavelengths of infrared radiation that are not absorbed by the atmosphere.
