Product Introduction
A Zero Order Waveplate(Quartz) is a special type of optical element also known as a zero-order phase retarder or zero-order polarizer. Its main function is to change the polarization state of light by creating an optical range difference (or phase difference) between two mutually orthogonal polarization components. This type of waveplate(Quartz) is characterized by the fact that its total delay is only a small fraction of that of the multiorder types, making the delay of a zero-order waveplate more constant relative to temperature and wavelength variations.
Common types of Zero Order Waveplates(Quartz) include glued Zero Order Waveplates and Air Gap Zero Order Waveplates. Glued Zero Order Waveplates(Quartz) are made by gluing two waveplates together, while Air Gap Zero Order Waveplates are connected by a bracket that creates an air gap between the two waveplates. Air Gap Zero Order Waveplates excel in high power laser applications in the UV band due to their high damage threshold and low dispersion.
