Description

This waveplate is a special kind of multi order waveplate. Dual wavelength waveplate is designed to be used in dual wavelength setups, for example, it can be operated as a quarter waveplate @1064nm and as a half waveplate @532nm at the same time. It's always used to manage the states of polarization of laser beams to obtain maximum conversion efficiency.

Feature

  • Thickness: < 2.0mm
