The problem of centering the long focal length interferometric objectives is discussed together with the method to control the optical quality of the system after the assembling process. The practical aspects of using the inverting confocal Fabry-Perot inteferometer for solving those problems are presented. The achievable accuracy is discussed and proved by testing the asymmetrical deformations of the wavefront behind the system under test. In the cases discussed the sensitivity of lens centering is of order of few seconds of arc. The asymmetrical wave aberration, is tested interferometrically using the FFT-technique for analysing the fringe pattern with accuracy of λ/80. The asymmetrical wave aberration of the system under test is equal to λ/38.
