Achromatic waveplate is made from two different substrate materials such as crystal quartz and magnesium fluoride. For the single material,waveplate’s working wavelength is very limited because of the dispersion of the material. But Achromatic Waveplate uses two different kinds of materials with the different dispersion. Such waveplate is not sensitive to the wavelength change.

Dual Wavelength Waveplate
Dual wavelength waveplate is a special type of multiple waveplate that provides a specific retardance at two different wavelengths, it’s particularly useful when used in conjunction with other polarization sensitive components to separate coaxial laser beams of different wavelength. It is widely used to improve conversion efficiency in solid double frequency laser device.
