Zero order waveplate WPA series

quartz

Air spaced zero order waveplate is constructed by two quartz plates installed in a mount, to form a air gap between the two quartz plates. 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 multiorder waveplates. ·Air Spaced ·Thickness 1.5~2mm ·Double Retardation Plates ·Broad Spectral Bandwidth ·Wide Temperature bandwidth ·Hight Damage Threshold ·AR coated and Mounted 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.
