Actual optical systems have increasing requirements on accuracy and cost reduction at the same time. This leads to high demands for the process control during production. For high precision lenses it is not unusual that centering accuracies of single lenses and mounted components are the limiting tolerances for the overall system performance. At the same time it is important that also for less demanding systems the most cost efficient production process can be identified. By applying sensitivity analysis methods, typically used in optical design, it is easy to achieve a deeper understanding of the centering process of cemented components. The relevant centering parameters and their respective sensitivity can be calculated for different manufacturing methods and the optimum overall process can be chosen by comparison.
