This thesis was digitized by the Institute of Optics in 2014 and was determined to have lapsed into the public domain.

Alternative designs using absorbing layers, particularly two absorbing layers, are investigated. The theory is outlined by which the maximum transmission at a desired wavelength can be obtained, for a Fabry-Perot type interference filter composed of two given metal layers separated by a dielectric spacer. A systematic procedure is presented for the design of a Fabry-Perot type filter of optimum transmission. The peak transmission for such a filter is twice as great as that for a conventional Fabry-Perot filter. In addition, the bandwidth is considerably narrower. Experimental transmission curves are presented for comparison with the maximum attainable transmission predicted by theory
