| Zero-Order
Waveplate |
|
|
|
|
| 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. Cemented zero order waveplate should used for
low power (<10MW/cm^2). Optical conteacted and airspaced
zero order waveplate are fit for high power laser applications
(>500MW/cm^2).

Conclusion: Zero order waveplate has wider
banwith and less sensitive to wavelength.
