Conclusions
The polyalkaline photocells meet the stability requirements for the “blue-red” ratio for a long time, provided the spectral sensitivity regions are rationally utilized. These photocells, owing to their high temperature stability, can be used in bichromatic pyrometers without special thermostatic control.
