Fuzhou Siaon Optoelectronic Technology Co., Ltd. provide Low order waveplate.Low order waveplate which can be replaced by mulit-order waveplate is designed to give a retardance of several full waves,The thickness is around 0.2 -0.5mm. Compared with zero order waveplate, Low order waveplate is more sensitive to wavelength and temperature changes, Retardation Tolerance is lower. However, they are less expensive and widely used in many applications where the increased sensitivities are not critical.
