INOUIRY
Multi-order waveplates are manufactured using high-quality quartz crystals and offer retardations of λ/2 and λ/4 for various commonly used wavelengths. Half-order waveplates are typically used to rotate the polarization state of light, while quarter-order waveplates are used to convert linearly polarized light into circularly polarized light.
Multi-order refers to the fact that, in addition to a retardation smaller than one wavelength, the optical path also includes several full-wavelength (also called order, or m) delays. Compared to zero-order waveplates, multi-order waveplates are highly sensitive to temperature, wavelength, and angle of incidence.
