Matters needing attention when using optical pyrometers

The effect of non-black body. Since the measured object is a non-absolute black body, and the blackness coefficient ελ of the object is not constant, it is related to the wavelength λ, the surface condition of the object and the temperature.

What is the difference between an infrared thermometer and an optical pyrometer?

The first is the difference in measurement range. Optical pyrometers measure high temperatures from 700°C to 3200°C. Infrared thermometers have a wider temperature measurement range, ranging from low temperatures of minus tens of degrees to high temperatures of 3000 degrees, which can be said to be more extensive.

Temperature measurement principle of optical pyrometer

Any object at high temperature will project a certain wavelength of electromagnetic waves (radiant energy). The visible light with a wavelength of 0.65μm electromagnetic wave is the most sensitive to human eyes, and the radiant energy of this wavelength changes significantly with temperature.
