Abstract
An interferometric method is used to evaluate the refractive index deviation in the infrared materials. The deformations of the surfaces on the sample are precisely measured by phase shifting interferometer working at 0.6328 micrometers and the errors introduced by the surface deformations are removed from the results. The accuracy of this method reaches the order of 10-5.
