ABSTRACT:
A birefringent waveplate that is composed of an integral, transparent, glass body, the glass body consisting of non-absorbing crystalline particles dispersed in a glassy matrix, the dispersed crystalline particles being selected from the group consisting of copper chloride, copper bromide and mixtures thereof, the dispersed crystalline particles having a high aspect ratio and being oriented and aligned along a common axis, whereby the waveplate is rendered birefringent so that polarized components of light transmitted through the waveplate have a phase shift introduced.
