Zero order waveplate WPC series

quartz

The zero order waveplate is designed to give a retardance of zero full waves, plus the desired fraction.Zero order waveplate shows better performance than multiple order wavepalte.It has broad bandwidth and a lower sensitivity to temperature and wavelength changes.It should be considered for more critical applications. Material Quartz Dimension Tolerance +0.0,-0.1 Wavefront Distortion <λ/8@633nm Retardation Tolerance λ/500 Parallelism <1 arc second Surface Quality 20/10scratch /dig Clear Apterure Central 90% AR Coating <0.2%@wavelength StandarWavelength:266nm,355nm,532nm,632.8nm,780nm,808nm,980nm,1064nm,1310nm,1550nm This type of zero order waveplate is constructed of two multiple order waveplate with their axes crossed.Thus the effect of the first plate is canceled by the second ,except for the residual difference between them, Cemented by Epoxy Better Temperature Bandwidth Wide Wavelength Bandwidth AR Coated,R<0.2%
