Abstract

In a multi-segmented optical device, the lengths and thermal properties of the segments are selected so that thermally induced changes in the optical path through the device are compensated. In particular, a birefringent optical device that includes at least two birefringent segments formed from different birefringent material on an optical path. The lengths of the segments are selected so that thermal effects on the birefingence of the optical path through the first birefringent segment are substantially compensated by thermal effects on the birefringence of the optical path through the other birefringent segments.
