1. Crystalline Quartz Waveplates

Features

Crystalline quartz waveplates are made from materials that have a birefringence property. Most common types are designed so that an ordinary ray will exhibit a half (λ/2) or quarter (λ/4) wave retardation with respect to an extraordinary ray. Such waveplates are used to rotate the plane of polarization, converting a linear polarization to a circular one and vice versa. Such elements are used for electro-optic modulations and as a variable ratio beam splitter when used in conjunction with a polarization cube. Although the latter two types of waveplates are the most common, we also offer custom retardation values on request.

One of the most common arrangements of the waveplates is the zero order (ZO) air-spaced version. These waveplates are built of two crystalline quartz plates with specific thicknesses and crossed axes, which results in a zero order performance. This arrangement allows us to reach a better performance for a wider wavelength range and is less sensitive to temperature changes when compared with low order (LO) waveplates. High purity crystalline quartz materials and precise parallelism between the two air-spaced plates allows the transmitted wavefront distortion to be better than λ/10 at 632.8 nm.

1. Low Order Waveplates

Low (multiple) order waveplate is designed to give a retardance of several full waves, plus the desired fraction. This result in a single, physically robust component with desired performance. However, even small changed in wavelength or temperature will result in significant changes in the desired fractional retardance. They are less expensive and find use in many applications where the increased sensitivities are not an important.

2. Zero Order Waveplates

The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction. Zero order waveplate shows better performance than multiple order waveplates. It has broad bandwidth and a lower sensitivity to temperature and wavelength changes. It should be considered for more critical applications.

4. Achromatic Waveplate

Achromatic waveplate is made from two different substrate materials such as crystal quartz and magnesium fluoride. For the single material waveplates the working wavelength is very limited because of the dispersion of the material. While two different kinds of material are used achromatic waveplate,  the dispersions of the birefringence are also different. Hence such waveplate is not sensitive to the wavelength change.
