Plane polarized beam is not welcomed in some circumstances such as reflecting spectrometer. A depolarizer will change the plane polarization into a mix of polarization states by scrambling up the polarization, the result is to change plane polarized beam into pseudo-depolarized beam and produce depolarization. Depolarizer is widely used in polarization sensitive instrument.

Hangzhou Shalom EO offers the custom depolarizers upon customer's request, and the stocked moudles are also available in fast delivery and low cost.
