Optimization of the width of the working spectral region of a video pyrometer

  • Published:
Journal of Applied Spectroscopy Aims and scope

We have obtained expressions allowing us to estimate the uncertainty in measurement of the temperature by a broadband video pyrometer in the case when the known value of the spectral emissivity of the object applies to the central wavelength of the working spectral region. We show that for monitoring industrial production processes, the working spectral region of the video pyrometer in a number of cases can be broadened up to 100–400 nm, which enables a many-fold increase in its sensitivity and a faster response time.
