Abstract

A brief outline will be given of several different numerical methods for the synthesis of interference filters with rather complicated spectral characteristics. With these it is possible now to design coatings having almost any desired transmittance curve. Unfortunately, the practical realization of such multilayer systems is often not easy. Frequently the thicknesses of the various layers of the coating assume different values. This necessitates the use of special thickness monitoring techniques during the construction of the filter. Also, the designs often call for refractive indices that are intermediate to those of known materials. Ways must be found to simulate materials with such indices. Other complications arise when the resulting multilayer filter is to be used in unusual environmental circumstances. Apparatus and methods will be described which are used at the NRCC for the construction of such filters.
