True Zero Order Waveplates, Optical Retarder, True Zero-order Quarter Wave plate, True Zero-order Half Waveplate

True zero-order waveplate is ideal case of waveplate. True zero-order waveplates are so thin that the optical phase delay between the two polarization directions is just 180° for a half-wave plate or 90° for a quarter-wave plate.

Features of True Zero-order Waveplates

- Large Angle Acceptance
- Low Temperature Sensitivity
- Wide Spectral Bandwidth

Comparison of Multi-order, Zero-order and 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 are 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):
