2.3 Thermal Sensors
2.3.1. Use of Nova II with thermal type sensors.
Most Thermopile sensors have somewhat different
absorption at different wavelengths. In order to
compensate for this, each sensor has been calibrated
by laser at several wavelengths. When you choose the
correct laser wavelength, the correction factor for that
wavelength is automatically introduced. Note that the
laser wavelength correction in use is displayed in the
upper left corner of the display.
Thermopile sensors with the LP1 absorber have large
variation of absorption at different wavelengths.
Therefore a continuous spectral curve is inserted into
the sensor, enabling the user to choose the desired
wavelength from the range specified in the
specification sheet and the correction factor for that
