When the radiation source in a Michelson interferometer is placed in front of or behind the focal plane of the collimator, distortions arise in the spectral line shapes. The appearance and behavior of these distortions in a cube-corner interferometer are treated in this work. We shall also present a simple and fast method to calculate the true line position of a distorted line, and an easy rule of thumb to connect the off-focus shift and the amount of distortion. Calculation of the phase-error curves in the signal domain is treated as well. This calculation gives a possibility of correcting the distorted interferogram.
