In high precise surface testing  temperature stability and uniformity are of paramount importance to the high accuracy of test results. Micro-temperature variation and temperature gradients not only cause the change of the air refractive index and lead to the optical path variation in interferometer cavity  but also result in deformation of the tested surface itself  which always brings about errors to the test results. Temperature effects on the interferometer cavity and the tested surface are analyzed from the axial and radial directions in this letter. Temperature model of the interferometer cavity and the tested lens are established and quantitative calculations and diagram of test results versus temperature and lens dimension are provided. It shows that temperature gradients effect increase with the length of the interferometer and the dimension of the tested lens. The interferometer cavity is mainly affected by radial temperature gradients while the tested lens is mainly affected by the axial temperature gradients. 2010 Copyright SPIE - The International Society for Optical Engineering.
