Achromatic Waveplates

Achromatic waveplates are made from two different materials: crystal quartz and magnesium fluoride with highly efficient broadband antireflection coatings.Since the dispersion of the
birefringence can be different for the two materials, it is possible to specify the retardation values at a wavelength range. Hence, the retardation of the resulting waveplate can be made
to low sensitivity to wavelength change. Based on the contact methods of two plates, we provide two types: Airspaced and cemented.
