Cemented Zero Order Waveplate is constructed by two quartz plates with their fast axis crossed, the two plates are cemented by UV epoxy. 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 Cemented Zero-Order Waveplate：
The cemented zero-order waveplate realizes zero-order phase retardation by laminating birefringent materials with optical adhesive, boasting notable technical advantages: a low-dispersion design ensures phase retardation error <5% across a 400-2000nm broad spectral range, with precision reaching λ/100 level. Its cemented structure enhances mechanical stability, supporting operation across a wide temperature range of -20℃ to 80℃, while maintaining a laser damage threshold >5 J/cm² (at 1064nm). In fiber-optic communication WDM systems, it synchronously stabilizes the polarization states of 1310/1550nm dual wavelengths, reducing polarization-dependent loss (PDL) to below 0.3dB. In femtosecond laser micro-nano processing, its low-dispersion characteristics prevent polarization state drift of pulsed light, ensuring polarization precision of ±0.1° for 800nm laser and facilitating improved repeatability and resolution of micrometer-scale processing linewidth.
Multiple order waveplate means the retardance of a light path will undergo a certain number of full wavelength shifts in addition to the fractional design retardance. The thickness of multi order waveplate is always around 0.5mm. Compared with zero order waveplate, multi order waveplate is more sensitive to wavelength and temperature changes. However, they are less expensive and widely used in many applications where the increased sensitivities are not critical. Features: Thickness: 0.2-0.5 mm High Damage Threshold Better Temperature Bandwidth Low Cost

Dual Wavelength Waveplate is an advanced optical component designed to precisely control the polarization states of two distinct laser wavelengths. It is widely used in laser technology, nonlinear optical systems, and precision optical instruments. Its core function is to provide predefined phase retardation at two specific wavelengths, optimizing polarization conversion efficiency and meeting the demands of complex optical systems.

Achromatic Waveplate is similar to zero order waveplate except that the two plates are made from different birefringent crystals. Since the dispersion of the birefringence of two materials is different, it is possible to specify the retardation values at a broad wavelength range. So, the retardation will be less sensitive to wavelength change. In other words, it can be used at a broadband wavelength range. Features： Epoxy Cemented or Air Spaced available Very Broad Bandwidth

Quartz Polarization Rotators offer 45deg or 90deg rotation at a number of common laser wavelength, the optical axis in a polarization rotator is perpendicular to the polished face of the optic. The result is that the orientation of in put linearly polarized light is rotated as it propagates through the device. Left-handed and right-handed rotators can be offered by MT-Optics,Inc.
