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.

We calculate the influence of temperature change on the refractive index of air  establish a model of air temperature distribution and analyze the effect of different temperature distribution on the high accuracy interferometric metrology. First  a revised Edlen formula is employed to acquire the relation between temperature and refractive index of air  followed by introducing the fixed temperature gradient distribution among the spatial grid within the optical cavity between the reference flat and the test flat of the Fizeau interferometer  accompanied by a temperature change random function within each grid. Finally  all the rays through the air layer with different incident angles are traced by Matlab program in order to obtain the final output position  angle and OPD for each ray. The influence of different temperature distribution and the length of the optical cavity in on the testing accuracy can be analyzed through the RMS value that results from repeatable rays tracing. As a result  the horizontal distribution (vertical to optical axis) has a large effect on the testing accuracy. Thus  to realize the high accuracy figure metrology  the horizontal distribution of temperature must be rigorously controlled as well as to shorten the length of the optical cavity to a large extent. The results from our simulation are of great significant for the accuracy analysis of interferometric testing and the research of manufacturing a interferometer. 2010 Copyright SPIE - The International Society for Optical Engineering.
