Abstract

Following a brief definition, it has been explored that a roof Dove prism is a typical circular beam deflector used in a transmitted parallel beam. The importance attached to this prism is apparent for its multifunction. However, the unfavorable value of the length-aperture ratio of the roof Dove for most popular optical glass has imposed restrictions on extending its application to many cases. To overcome the difficulty, a new type of roof Dove, i.e., a square-sectional roof Dove prism and its equivalent are suggested, and on this basis have been built up two kinds of prism array to greatly reduce the length-aperture ratio. The potential of these new types of reflecting prism and reflecting prism array will rely on the development of the fabrication technique as well as on the further researches.
