Waveplate

United photonics Technology Zero Order Waveplate-Optically Contacted 光胶零级波片 Optically Contacted zero order waveplate is constructed by two quartz plates with their fast axis crossed, the two plates are constructed by optically contacted method, the optical path is epoxy free. The difference in thickness between the two plates determines the retardation. Zero order waveplates offer a substantially lower dependence on temperature and wavelength change than multi order waveplates. ·Optically Contacted ·Thickness 1.5~2mm ·Double Retardation Plates ·Broad Spectral Bandwidth ·Wide Temperature bandwidth ·Hight Damage Threshold Specifications: Material:Quartz Diameter Tolerance:+0.0, -0.1mm Wavefront Distortion :λ/8 @ 632.8nm Retardation Tolerance:λ/300 Parallelism:<3 arc second Surface Quality:20/10 Clear 90%">Aperture:>90% Coating:S1&S2: R<0.2% @ wavelength Standard wavelength: 266nm, 355nm,532nm, 632.8nm, 780nm,808nm, 850nm, 980nm,1064nm, 1310nm, 1480nm, 1550nm Half Waveplates P/N# Quarter Waveplates P/N# Diameter(mm)   Note：   •  Custom designs for other sizes and coatings are also available upon request.   •  UPT’s standard coatings are available.   •  Other waveplates with different wavelength range are also available upon request, please contact UPT for more information.
