Optical Isolator With High Isolation
Our Optical Isolator With High Isolation products are popular in the market. Optical isolator is a combination of a polarization Beam splitter cube ( PBS ) and a quarter wave plate made of crystal quartz. Incident light is linearly polarized by PBS and converted to circular polarization by the quarter wave plate, it only allows light to travel in one direction. If any portion of the emerging beam is reflected back into the isolator, the quarter wave plate 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.

Crystalline Quartz Polarization Rotator
Our Crystalline Quartz Polarization Rotator products have been recognized by our customers with advanced production technology and good quality. Due to the rotation activity of natural quartz crystal, it also can be used as polarization rotators so that the plane of input linearly polarized beam will be rotated at special angle which is determined by the thickness of quartz crystal. Left-handed and right-handed rotators can be offered by Coupletech Co., Ltd. Crystal Quartz Polarization Rotator is made of quartz from 200nm to 2500nm. This kind of Polarizing Optic is up to 100mm diameter, as custom rotation angle available.

High Quality Glan Taylor Polarizer
We have many years of experience in the production of High Quality Glan Taylor Polarizer. Glan Taylor prism polarizer is made of two same Birefringent Crystals material prisms that are assembled with an air space. Its length to aperture ratio which is less than 1.0mm makes it a relatively thin polarizer. Glan Taylor Prisms with no side escape windows are suitable for low to medium power application where the side rejected beams are not required. The angular field of different materials of polarizers is listed below for comparison.

Rochon Prism Polarizer Quartz
We are experts in the field of Rochon Prism Polarizer Quartz. Rochon polarizer is made of two Birefringent materials prisms ( e.g. Birefringent Crystals materials: A-BBO, Calcite, YVO4, Quartz ) cemented together, which be part of Polarization Optics. Both ordinary and extraordinary beams propagate collinearly down the optic axis in the first prism under the ordinary refractive index. Upon entering the second prism the ordinary beam experiences the same refractive index and continues undeviated. The extra-ordinary beam, however, now has a lower refractive index and is refracted at the interface. The angle of refraction is further increased at the birefringent material/air exit surface. Any separation angle can be designed for specific wavelength upon customer's requests. Coupletech provid......

Wollaston Prism Polarizers Quartz
Our Wollaston Prism Polarizers Quartz products are popular in the market. Wollaston Prism Polarizer is made of two Birefringent materials prisms ( e.g. birefringent crystal materials: YVO4, a-BBO, Quartz, Calcite ) that are cemented together. It is an excellent kind of Polarizing Optic. The deviations of the ordinary and extraordinary beams are nearly symmetrical about the input beam axis, so that Wollaston Polarizing Beam Splitter has approximately twice the deviation of the Rochon. The separation angle exhibits chromatic dispersion, as shown in the blow. Any separation angle can be designed upon the requirement. The separation angle of standard products versus wavelength is shown in the plot below. Moreover, Coupletech aslo pruduce other kind of Laser Component, such as Pockels Cell Driv......

Glan Thompson Polarizer Calcite or a-BBO Prisms
Our Glan Thompson Polarizer Calcite or a-BBO Prisms products are your best choice! Glan Thompson polarizer is made of two calcite prisms or a -BBO prisms cemented together, which belongs to Polarization Optics. It is a kind of common Optical Element. Two types of Glan Thompsons are available, one is the standard form and the other is the long form. Their length to aperture ratios are 2.5 : 1 and 3.0 : 1 respectively. Glan Thompsons tend to have higher extinction ratio than air spaced polarizers. In the ultra violet spectrum, their transmission is limited by absorption in birefriengent materials as well as the cement layer. a -BBO polarizers and Calcite polarizers can be used from about 220 to 900nm and 350 to 2300 nm respectively.
