We developed a scanning Hartmann sensor and an interferometer detector for precision measurements of thermal effects in samples in vacuum are developed. The simultaneous use of these methods allowed us to distinguish contributions of different thermal effects. Besides we discussed active thermal correction of thermally induced wawefront distortions by means of ancillary heating using CO2 laser irradiation.
