Micro Singlet True Zero Order Waveplates

Zero Order Waveplates should be considered for more critical applications. The advantages of a Zero Order Waveplate are an increased bandwidth and a lower sensitivity to temperature changes. A ± 2% change from the design Wavelength will cause only a minor change in retardation of a Zero Order Wave-plate. With a multiple Order Wave-plate, a ± 1% change from the designed wavelength will cause considerable problems with the retardation. AZURE manufacture many kinds of singlet true zero order waveplates of special sizes to meet your application requirements.
