The optris PI 450 and optris PI 640 infrared cameras can now also be calibrated for a temperature measurement range of up to 1500 °C. This allows the two high-resolution cameras to be integrated into applications which far exceed the previous threshold of 900 °C. These camera models feature an impressive dynamic range from 200 °C to 1500 °C, thus extending their possible applications. In heat treatment processes and high temperature processes in particular, continual measurement without switching range is now possible.

The application fields are the steel industry where the inner walls of combustion chambers are tested and processes of selective laser melting. Another application is in processes which have to be controlled or regulated across a wide temperature range. The glass industry is an example of this. Molten glass has a temperature of around 1000 °C, whereas the material cools down to less than 500 °C by the end of the process.
