Fuzhou Siaon Achromatic Waveplate Suppliers and Manufacturers

Fuzhou Siaon Optoelectronic Technology Co., Ltd. provide Achromatic waveplate 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.   Material: Quartz+MgF2 Dimension Tolerance:+0.0, -0.1mm Clear Aperture: >90% Wavefront Distortion: λ/4@632.8nm  Surface Quality: 40-20  Parallelism:< 10 arc sec Retardation Tolerance: λ/100 Coating: AR Coating Mount:Black Anodized Aluminum

Achromatic Waveplate Achromatic waveplate is made from two different substrate materials such as crystal quartz and magnesium fluoride. For the single material,waveplateâ??s working wavelength is very limited because of the dispersion of the material. But Achromatic Waveplate uses two different kinds of materials,with the different dispersion, such waveplate is not sensitive to the wavelength change. Dual Wavelength Waveplate Dual wavelength waveplate is a special type of multiple waveplate that provides a specific retardance at two different wavelengths, itâ??s particularly useful when used in conjunction with other polarization sensitive components to separate coaxial laser beams of different wavelength. It is widely used to improve conversion efficiency in solid double frequency laser device. Polarization Rotator 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.

United Photonics Technology Waveplates Principle Application 4 Waveplate UPT quarter waveplates create a quarter-wavelength phase shift 2, 90 and can convert linear polarization to circular polarization and vice versa. They are often used with a linear polarizer to form an isolator, blocking light reflected back from other surfaces (ellipsometry, optical pumping, isolation). UPT half waveplates retard one polarization direction by half a wavelength 180, effectively changing the direction of linear polarization, depending on the orientation of incident linear polarization with respect to the crystal axis. Therefor they can be used as continuously adjustable polarization rotators e.g. in electro optical modulation or as a variable beam splitter when used in combination with a polarizing beam splitter.
