Glan Taylor Polarizer is a device that produces linearly polarized light from light of other states of polarization.It consists two same birefringence material prisms which are separated by an air space.Glan taylor polarizer will divide an entering unpolarized beam into beam rays,one is the extraordinary that is transmitted through the other side,another is the ordinary ray that is totally internally reflected and absorbed.   Features: Air-Spaced Close to Brewster's Angle Cutting High Polarization Purity Short-Length Suitable for Low Medium Power Application  

Glan Laser Prisms is a glan taylor polarizer that is specially designed for high energy application. The side of housing are drilled two holes. The ordinary ray is reflected through an angle and exits the polarizer through one of holes.   Features: Air-Spaced Close to Brewster's Angle Cutting High Polarization Purity Mounted with escape window Suitable for High Power Application  

Wollaston polarizer can separate an incident beam into two rays: extraordinary and ordinary ray with a deviation angle which is dependent on wavelength. Both rays are transmitted through the other surface.   Features: Cemented or Optically Contacted Separate ordinary and extraordinary beams at certain angle Suitable for low power application and where the large deviation is required

Rochon polarizer separates incident beam into ordinary ray and extrordinary ray like wollaston polarizer, but extraordinary ray is straight transmitted through, while ordinary is transmitted with a deviation angle.   Features: Optically Contacted High Polarization Purity Suitable for Low or High Power Application

Glan Thompson polarizing Beamsplitter Cubes uses two cemented calcite prisms to separate unpolarized light into s-polarized (45° deflected) and p-polarized (transmitted) beams with 90%+ transmission in a rectangular metal housing, ideal for applications requiring dual linear polarization states like interferometry and laser systems.   Features: Cemmented High Polarization Purity High Transmission Suitable for Low Power Application Split o-ray & e-ray at 45deg

Polarization Beam Displacer is used to separate an unpolarized beam into two orthogonally polarized output beams which are parallel to each other. The ordinary polarization transmits straight through while the extraordinary walks off from the ordinary beam. It can be used as polarizing Beamsplitter. Polarization beam displacer can also be used to combine two orthogonally polarized beam. The most widely used materials for Polarization Beam Displacer are Yttrium Vanadate (YVO4), a-BBO, Calcite and etc. Features: Working Wavelength 350-4000nmYVO4, a-BBO, Calcite availableOrthogonally Polarized Outputs, Outputs Parallel to InputHigh Extinction Ratio (>105)

Polarization Beam Combiner is made of two pieces YVO4 prism. The calcite polarization combiner can be with 45° of two polarization beam input. Please refer to Gian Thompson Polarizing Beamsplitter Cube which is made of calcite can also work as polarization beam combiner. But since it is glue cemented, the damage threshold is lower. While we specially design the air spaced Polarization Beam Combiner which is made of YVO4. The Angle between two input polarization beam is 100.6 deg. All the input & output surfaces are optical polished and coated.   Features: Air Spaced High Damaged Threshold Broad Band for 500-4000nm

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  

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.   Features: Optically Contacted Thickness 1.5~2mm Double Retardation Plates Broad Spectral Bandwidth Wide Temperature bandwidth Hight Damage Threshold

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.   Features: Air Spaced Thickness 1.5~2mm Double Retardation Plates Broad Spectral Bandwidth Wide Temperature bandwidth Hight Damage Threshold AR coated and Mounted

This type of zero order waveplate is constructed of a true zero order waveplate and a BK7 substrate as the waveplate is very thin and easy to be damaged,the BK7 plate's function is to strengthen the waveplate.   Features: Broad Spectral Bandwidth Wide Temperature Bandwidth Wide Angle Bandwidth Cemented by Expoy

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.

Polarizing Cube Beamsplitters split randomly polarized beams into two orthogonal,linearly,polarized components. S-polarized light is reflected at a 90deg.Angle while P-polarized light is transmitted. Each beamsplitter consists of a pair of precision high tolerance right angle prisms cemented together with a dielectric coating on the hypotenuse of one of prisms.

Non polarizing Beamsplitter Cube consists of a pair of precision high tolerance right angle prisms cemented together with a metallic-dielectric coating on the hypotenuse of one of the prisms. The low polarization dependence of the metallic-dielectric coating allows the transmission and reflection for S- and P- polarization states to be within 5% of each other. This means that they will not change the state of polarization of the incident beam. We offer both broadband and single wavelength non-polarizing cube beamsplitters (NPBS). An antireflective coating has beem applied to each face of the beamsplitter in order to produce maximum transmission efficiency for the appropriate wavelength range.

Optical isolator is a combination of a polarization Beamsplitter cube (PBS) and a quarter waveplate made of crystal quartz. Incident light is linearly polarized by PBS and converted to circular polarization by the quarter waveplate. If any portion of the emerging beam is reflected back into the isolator, the quarter waveplate will convert the reflected beam into a linearly polarized beam which is perpendicular to the input beam. This beam is then blocked by PBS and it will not return to the input side of the system.   Feature:Block optical feedbackPassive isolation of linearly polarized lightHigh isolationRoHS Compliant

Thin Film Linear Polarizer Composed of front and rear N-BK7 glass substrates with an intermediate linear polarizing film, this component offers two mounting options: retaining ring and rotating mount. Across the entire optical surface, the transmission axis orientation is uniform, enabling the generation of a linearly polarized light beam with a specific polarization direction. It ensures a high extinction ratio and operates effectively over a wide angle of incidence range.
