Dual Wavelength Waveplate
Description:
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.
Applications:
Widely used on Third Harmonic Generation (THG) system.
