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.

Technical Advantages of Optically Contacted Zero-Order Waveplat:
The optically contacted zero-order waveplate achieves zero-order phase retardation through optical contact of precision-polished surfaces of birefringent materials, boasting notable technical advantages: its adhesive-free design eliminates dispersion and aging issues associated with optical adhesives, achieving λ/100-level phase retardation precision (phase error <1%) and wavelength dependence <2% across a broad 400-1800nm spectral range. Benefiting from its molecular-level contact interface, it exhibits excellent mechanical stability, supporting operation across a wide temperature range of -40℃ to 85℃ with retardation variation <2.5%. Its laser damage threshold exceeds 5-10 J/cm² (1064nm, 10ns), surpassing that of cemented structures by over 3 times.In femtosecond laser oscillators, its zero-dispersion characteristics ensure polarization state consistency across supercontinuum spectra from 400nm to 1030nm, with pulse chirp error <5%. In quantum key distribution (QKD) systems, its high-precision phase control maintains polarization state fidelity above 99.8%, facilitating low-bit-error-rate quantum signal transmission.
