Zero Order Waveplate

Zero Order Waveplate

  • Double Retardation Plates
  • Broad Spectral Bandwidth
  • Wide Temperature bandwidth
  • Hight Damage Threshold

Zero Order Waveplates are made from two quartz plates with their fast axis crossed, there are three types of zero order waveplates, cemeted zero order waveplate, air space zero order waveplate and optically contacted zero order waveplate.

Standard wavelength:
266nm, 355nm, 532nm, 632.8nm, 780nm, 808nm, 850nm, 980nm,1064nm, 1310nm, 1480nm, 1550nm
