Low Order Waveplate

Low-level waveplates are machined from a single piece of quartz crystal, producing phase delays of several orders to the design wavelength. The thickness is generally around 0.3mm, the wavelength bandwidth is narrow, and the temperature stability and field of view are not as good as zero-order waveplates. It can be used in light source systems with good monochromaticity.
