�� How to Select a Proper Waveplate

                Below is a compare of all kinds waveplates, from which it may be helpful for you to choose a proper waveplate needed.

Waveplate Type	Damage Threshold	UV Range wavelength	Mounting	Other
Multi Order, Single Plate	1GW/cm2	Can design at UV range	Without mount. Mount is optional.	Sensitive to temperature change and incidence angle. For low accuracy use.
Zero Order, Cemented Type	10MW/cm2	Can not design for UV range because the glue has an absorption at UV range	Without mount. Mount is optional.	Has good performance to resist the effect of temperature change and incidence angle change.
Zero Ordr, Optical Contact Type	Higher than cemented, but lower than airspaced	Can design at UV range	Without mount. Mount is optional.	Has good performance to resist the effect of temperature change and incidence angle change.
Zero Order, Airspaced Type	500MW/cm2	Can design at UV range	Has to be with mount	Has good performance to resist the effect of temperature change and incidence angle change.
Ture Zero Order, Cemented	10MW/cm2	Can not design for UV range because the glue has an absorption at UV range	Without mount. Mount is optional.	Has excellent performance to resist the effect of temperature change and incidence angle change.
True Zero order, Single Plate	1GW/cm2	Can not do for thickness less than 0.03mm. Prefered thikcness >0.05mm	Without mount. Mount is optional.	Has  excellent  performance to resist the effect of temperature change and incidence angle change.

Note: All damage Threshold mentioned above is for reference only. Different wavelength, Damage threshold should be different.
