Low Order Waveplate
Description
A waveplate or retarder is an optical device that alters the polarization state of a light wave travelling through it. Two common types of waveplates are the half wave plate and the quater wave waveplate.
Waveplates are constructed out of a birefringent material, such as quartz, for which the index of refraction is different for different orientations of light passing through it.
The beavior of a waveplate depends on the thickness of the crystal, the wavelength of the light and the variation of the index of refraction.

Frequently Asked Questions
A waveplate or retarder is an optical device that alters the polarization state of a light wave travelling through it.
Waveplates are constructed out of a birefringent material, such as quartz, for which the index of refraction is different for different orientations of light passing through it.
When you order the waveplates, you need to know the following important parameters: 1) What is the wavelength? 2) What is the retardance? Half waveplates or quarter waveplates or some special type? 3) What is the order?
Low order compared to zero order, zero order has more broad wavelength and temperature and angle bandwidth. For zero order, true zero order and air spaced and optical contacted type have large damage threshold. But true zero and optical contacted type are more difficult to produce. Cemented type has low damage threshold.
Waveplates have applications in laser optics.
