Features of True Zero-order Waveplate

Comparing Multi-order, Zero-order & True zero-order waveplate

Multi-order waveplate, Zero order waveplate and True zero order waveplate are interchangeable for most of applications. For some critical applications, Zero order waveplate and True zero order waveplate should be considered. The advantages of zero-order waveplate are an increased bandwidth and a lower sensitivity to temperature changes.

However, the normal two plates design Zero order waveplate has a relatively larger thickness which reduces the field angle. For the applications where a large field angle is necessary, such as imaging systems, true zero order waveplate gives the solution. These true zero order waveplates are made of a very thin plate or cemented with a BK7 substrate, which ensures the best possible field angle, temperature and wavelength performance.

The following table gives the comparison of low order waveplate, zero order waveplate and true zero order waveplate(based on 1/2 @1064nm with 1/100 retardation variation):

Type of Waveplate	Multi-Order	Zero Order	True Zero Order
Temperature Sensitivity (nm/°C)	0.05	0.006	0.006
Spectral Bandwidth (nm)	6.1	42.6	42.6
Acceptance Angle (deg.)	8	4	23
