Dual wavelength Waveplates
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. Mounted Waveplates are available. (See Holder Size)
