Paper Abstract

Optical systems are designed to provide a specific functionality. However, a built optical system shows some deviations from the nominal performance caused by the manufacturing process. This tutorial will demonstrate the tolerancing process using Nijboer-Zernike polynomials as an expression of wave front aberrations. Nijboer-Zernike polynomials are a special form of well-known circle polynomials developed by Zernike. They are orthogonal and have an automatic balancing of aberrations of various orders. The degradation of the Strehl Ratio can be estimated very easily for every single aberration using the value of the specific coefficient. This property is very beneficial for the definition of a tolerance budget.
