Cemented &Optically Contacted Zero-order Waveplates
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. Because it is cemented, the damagethreshold must be considered(about 10MW/cm2)when used.
