Achromatic Zero-Order Waveplates

Achromatic Zero-Order waveplate is made from two different substrate Material such as crystal quartz and magnesium fluoride. For the single material waveplates the working wavelength is very limited because of the dispersion of the material. While Achromatic Zero-Order Waveplate use two different kinds of material, the dispersions of the birefringence are also different. Hence such waveplate is not sensitive to the wavelength change.

   CASTECH design Achromatic Zero-Order Quartz-MgF2 waveplates with working wavelength range larger than 300nm and retardation accuracy better than λ/50 for λ/2 waveplate and better than λ/100 for λ/4 waveplate.

Main advantages:

         ?   Extremely broad wavelength ranges

         ?   High damage threshold for Air-spaced Achromatic Zero-Order waveplate

         ?   Low sensitivity within the designed wavelength

         ?   Retardation tolerance up to λ /100 over the wavelength range


CASTECH can offer two kinds of Achromatic Zero-Order Waveplates:Air Spaced and Optically Contacted Achromatic Zero-Order Waveplates.
