Abstract

In choosing the proper technique for testing the optical figure of a high-performance aspheric mirror, it is appropriate to prepare a complete error budget for the test and to analyze the individual elements thereof to ensure that the measurement uncertainty is within acceptable limits. Such an error budget has been defined for the Hindle Shell test of a convex hyperboloidal secondary mirror for a hypothetical high-performance Cassegrain telescope system. A residual figure error of λ/80 rms at λ = 0.6328 μm is assigned to this mirror. This paper establishes the rationale for the error budget and develops specifications for the test system and equipment components. The importance of measuring and subtracting the error contributions of the test set-up and of data processing to remove certain systematic errors is pointed out.
