Paper Abstract

Most optical setups used for accurate angle measurement have only a limited measurement range. An extension in which the total range is increased to a theoretical range of +90 to -90 deg (one-prism setup) or +60 to -60 deg (two-prism setup) with an angular resolution of 3.34 x 10-5 deg is presented. The accuracy is also discussed.
