| Abstract: | This paper discusses several principles of determination of the crystal elements' orientation arrangement in adjustable-wavelength birefringent filters. By using these principles, we-are able to determine the relations of the orientations among the birefringent crystal plates, the waveplates and the rotated 1/2 waveplates simply, clearly and accurately without any complicated mathematical calculations. |
