Quartz waveplate GCL-0607 series

zero order

Crystalline quartz is frequently used for the stringest quality retardation applications. Zero-order waveplate is made by cementing two quartz plates with their fast axes orthogonal to each other. The difference in thickness is equal to either /4 or λ/2 for a specified wavelength, Compared with multiple-order quartz retarders, they are much more insensitive to wavelength, temperature and angle of incidence. Waveplates of other wavelength and sizes are avalible for custom made. •Diameter： φ25.4+0.0/-0.15 •Retardation Accuracy： λ/500
