Dual Wavelength Waveplates

Featured Product from CeNing Optics Co., Ltd.


Dual wavelength waveplates are multiple order waveplate that provide a specific retardance at two different wavelengths. Its application is separation of different wavelengths with a polarization beamsplitter by rotating the polarization of one wavelength by 90°, and leaving the other unchanged.
