The starting point for the manufacture of many specialised optical components such as waveplates and etalons is a highly polished, parallel optical blank. In the case of etalons in particular, the ultimate performance is limited by the flatness and parallelism of the blank and the uniformity and reflectivity of the coatings applied to it.
In common with all manufacturing processes, a crucial element in cost effective, repeatable and high yield production lies in the availability of suitable measurement and Q.A. tools.
Etalon Master is such a tool. It represents a substantial improvement over other methods and enables optical components to be produced to closer tolerances than ever before.
