Zusammenfassung:	An electric circuit for a microscope includes a lock-in amplifier. The lock-in amplifier has an input for an input signal, an input for a reference signal, an output for an output signal and a bandwidth filter configured such that a low bandwidth frequency value and/or a high bandwidth frequency value is variably settable. A dynamic bandwidth controller is configured to receive at least one parameter of a current setting of the microscope as an input, and to control the low bandwidth frequency value and/or the high bandwidth frequency value of the lock-in amplifier as a function of the at least one parameter of the current setting of the microscope.
