It is constructed of two multi-order waveplates with their axis crossed. Thus, it performs as a zero-order waveplate because of the effect of two plates counteracting each other. It has wide temperature bandwidth and wavelength bandwidth properties.Its performance is as good as cemented zero-order waveplate. Additionally, the air-spaced construction enables, it is suitable for the high power laser application.
