A birefringent waveplate is composed of an integral, transparent, glass body having a thermally developed dispersed phase therein composed of particles having a high aspect ratio and being oriented and aligned in one direction, whereby the glass body is rendered birefringent so that polarized components of light transmitted through the glass body have a phase shift introduced.
