Influence of the window of cryogenic interference set up (CIS) on the light wave front was studied. Main factors which govern wave front distortion by the window were simulated. A method was developed for preliminary theoretical model analysis of these factors. Original method of laboratory control of the window before its installation into the CIS is suggested. The choice of the main distorting factors was determined by two characteristic regimes of CIS operation (vacuum and gas-filled). Comparison of theoretical calculations with experimental data suggests that the models proposed are adequate.
