Cemented Zero Order Waveplate:

Cemented Zero Order Waveplate is made of two multiple order waveplates. Comparing with single multiple waveplates, such technic could decrease the sensitivity of waveplate retardance to wavelength and incident angle. Our cemented zero order waveplates are made of quartz crystals and the retardance includes λ/2 and λ/4. For applications with a greater than +/-1% deviation, zero order waveplates are recommended due to their increased bandwidth and lower sensitivity to temperature change.
