In a typical system, Lepton cameras will typically achieve temperature measurement accuracies as defined in the Lepton datasheet, that is, +/- 5 degrees. In order to achieve better accuracies, contributions to accuracy from the final system must be considered. The design must not subject the Lepton to varying thermal effects. Also, calibration parameters can be created for the Lepton as installed in the final system. This can either be done based on a sample of these systems, or, for the best accuracy, calibration can be performed on individual units. This allows compensation for the window used, and thermal effects from nearby electronics. Details are provided in the Lepton with Radiometry datasheet.
