Dual Wavelengths Waveplate

Optics >>> Waveplate >>> Dual Wavelengths Waveplate

Dual Wavelength waveplate is a multiple waveplate that provide a specific retardance at two different wavelengths.  It is particularly useful when used in conjunction with other polarization sensitive components to separate coaxial laser beams of different wavelength.
