Waveplate Polarizing Optic ─Waveplate OverviewPolarizer WaveplateDepolarizer Waveplate OverviewBrewster Window Waveplates (retarders) are made from birefringent materials θ which introduce a phase difference between the fast and slow Optical Axis Quartz Polarization principal axis of the waveplate. The optical axis of waveplate is 2θRotator parallel to the face. Light incident normal to the surface will be split to components polarized parallel and perpendicular to the 45oOptical Isolator optical axis with different refractive index and velocity in this Optical Axis device. The difference in velocities gives rise to a phase shift Lateral Displacement which is called retardance. At any specific wavelength thePolarization Beamsplitter phase retardance is governed by the thickness of Waveplates. The standard waveplates we provided include half waveplates and quarter waveplates, other custom waveplates can also be provided upon request. Half Waveplate When applying a linearly polarized beam to a half waveplate, it emerges as a linearly polarized beam but its polarization plane is rotated with respect to the polarization plane of the input beam. The rotation of the polarization plane is such that the angle between the input polarization and the output polarization is twice the angle between the input polarization and the waveplate's axis. When applying a circularly polarized beam, a clockwise circular polarization will transform into a counter-clockwise circular polarization and vice versa. Half waveplates are often used as continuously adjustable polarization rotators and as a variable ratio beamsplitter when used in conjunction with a polarization beamsplitter cube. Quarter Waveplate When applying a linearly polarized beam with the polarization plane aligned at 45deg to the waveplate's principal plane, the output beam will be circularly polarized. Similarly when applying a circularly polarized beam to a λ/4 waveplate the output beam will be linearly polarized. When a quarter waveplate is double passed, i.e. by mirror reflection, it acts as a half waveplate and rotates the plane of polarization to a certain angle. Quarter waveplates are widely used in creating circular polarization from linear or linear polarization from circular, ellipsometry, optical pumping, suppressing unwanted reflection, optical isolation and etc.72 Tel:+86 27 87531505 Fax:+86 27 87531525 Email:[email protected] Http://www.u-optic.com

Polarizing Optic ─Achromatic Waveplate Achromatic WaveplateWaveplate 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 ф materials is different, it is possible to specify the retardationPolarizer values at a broad wavelength range.

This loss is avoided in the Brewster type (PBI Series) by presenting the P-polarized transmitted beam to these interfaces at Brewster's angle. The result is a high power, low loss polarizer that does not need AR coating. The user should be aware of two important considerations in the using of Brewster Polarizer. Firstly, we must use collimated beam only mainly as the stringent angular acceptance requirement. Secondly, the transmitted beam has a relatively large displacement with respect to the incident beam, but they are parallel.84 Tel: +86 27 87531505 Fax:+86 27 87531525 Email:[email protected] Http://www.u-optic.com

Polarizing Optic ─ Quartz Wedge DepolarizerDepolarizer WaveplateQuartz Wedge Depolarizer PolarizerPlane polarized beam is not welcomed in some circumstances such as reflecting spectrometer. A depolarizer will change Depolarizerthe plane polarization into a mix of polarization states by scrambling up the polarization, the result is to change planepolarized beam into pseudo-depolarized beam and produce depolarization. Depolarizer is widely used in polarizationsensitive instrument.Union Optic’s quartz wedge depolarizer consists of two 3° wedges of crystal quartz. Usual wedge depolarizer consists ofone crystal quartz wedge and a compensation fused silica to avoid big beam deviation, but the deviation is also very big forsome precise instruments. Union Optic does not use fused silica plate to compensate the beam deviation, we use a crystalquartz plate with its optical axis along the propagation direction. Because the depolarizer is constructed by same material,so the beam deviation can be much better. The usual depolarizer can only be used at narrow band wavelength to avoid thebig beam deviation. With our special design, our depolarizer can be used in a wide range of wavelength and keep thebeam deviation in an acceptable range.When a beam hits on the depolarizer, there is a variable phase shift across the beam aperture on the wedge, so apolarized beam can be effectively depolarized. Quartz wedge depolarizer can work well with monochromatic andbroadband light source.Usually we can get better result if we orient the input polarization state 45deg to the optical axis ofthe depolarizer. And also the effectiveness of the depolarizer increases with the size of the beam cross-section.Better At 45deg Optical Axis Alignment Quartz Brewster WindowIdeal for >Φ6mm Monochromatic Light & Broadband Light QuartzEpoxy Cemented or Optically Contacted AvailableSpecifications Quartz+Quartz Quartz Polarization +0/-0.2mm Rotator Material ±0.2mm Dimension Tolerance 60/40 scratch and dig Optical Isolator Thickness Tolerance <1 arc minute Surface Quality <3 arc minutes Parallelism < /[email protected] Beam Deviation 0.5 /mm@1064nm Flatness >90% central Retardation Uncoated Clear Aperture Cemented:>500mJ/cm2, 20ns, 20Hz @1064nm Coating Optically contacted：>5J/cm2, 20ns, 20Hz @1064nm Damage ThresholdStandard Product Lateral Displacement Polarization Beamsplitter Part No. Material Dimension Thickness Type Wavelength (mm) (mm) (nm)QWD3225 Crystal Quartz 25.4 5.0 CementedQWD3325 Crystal Quartz 25.4 5.0 Optically Contacted 400-2500 220-2500Http://www.u-optic.com Email:[email protected] Fax:+86 27 87531525 Tel:+86 27 87531505 95

Waveplate Polarizing Optic ─Polarizer Quartz Lyot DepolarizerDepolarizer Quartz Lyot Depolarizer Quartz QuartzBrewster Window Plane polarized beam is not welcomed in some circumstances such as reflecting spectrometer. A depolarizer will change the plane polarization into a mix of polarization states by scrambling up the polarization, the result is to change plane polarized beam into pseudo-depolarized beam and produce depolarization. Depolarizer is widely used in polarization sensitive instrument. Union Optic's quartz Lyot depolarizer converts a polarized beam into a pseudo-random polarized beam. Regarding Linearly polarized beam from a monochromatic source, the output beam is converted to pseudo-depolarized beam with polarization state varies spatially. Linearly polarized beam comes from a broadband source which is transmitted through a quartz Lyot depolarizer will have a polarization that varies spatially as well as with wavelength.Union Optic's quartz Lyot depolarizer consists of two crystal quartz wedges, the thickness of one is twice of the other. The optical axis of each wedge is in the plane of aperture, the orientation angle between two optical axes is 45°. The unique design of the quartz Lyot depolarizer does not require orienting the optical axes of a depolarizer at a specific angle, which is especially useful where the initial polarization state of the light is unknown or varies with time. Regarding monochromatic light, we can only get good pseudo-random polarization when the input diameter is bigger than 6mm. The minimum beam diameter requirement comes from that randomization of the output beam's polarization is achieved by producing a spatial variation when the light hits on the wedge surface.

Polarizing Optic ─Optical IsolatorOptical IsolatorOptical isolator is a combination of a polarization Beamsplitter cube (PBS) and a quarter Waveplatewaveplate made of crystal quartz. Incident light is linearly polarized by PBS and converted tocircular polarization by the quarter waveplate. If any portion of the emerging beam is reflectedback into the isolator, the quarter waveplate will convert the reflected beam into a linearlypolarized beam which is perpendicular to the input beam. This beam is then blocked by PBS andit will not return to the input side of the system.
