Abstract—
A setup for measuring the spectral dispersion of the external quantum efficiency in a wide temperature range is described. The setup is capable of monitoring variations in the luminous flux power and making corrections in calculations of the quantum efficiency. The absence of the second optical channel for monitoring variations in the light power is a distinctive feature of the setup. Owing to this feature, it is possible to eliminate mobile parts in the setup, which simplifies the design and does not require synchronizing devices.
