Product DescriptionProduct DescriptionBrewster windows are optical components with unique properties, designed based on Brewster's law. When unpolarized light strikes the interface between two different media at the Brewster angle, the reflected light becomes completely linearly polarized, and the reflected and refracted rays are perpendicular to each other. Brewster windows take advantage of this phenomenon and are typically made from specific optical materials, with precisely processed surfaces to ensure that light enters at the Brewster angle.SpecificationPRODUCT NAMEOptical WindowDIAMETER0.2-300mmTHICKNESS0.1-100mmDIMENSION TOLERANCE+/-0.1mm or +/-0.02mmSURFACE QUALITY60/40, 40/20,20/10 or betterCLEAR APERTURE>85%, >90%COATINGAR, BBAR or CustomMechanical and Chemical PropertiesFrom a material standpoint, Brewster windows can be fabricated from various optical substances such as glass and quartz. Each material offers distinct optical characteristics—glass provides good optical homogeneity and lower cost, while quartz delivers higher refractive index and superior chemical stability, making it suitable for applications demanding high optical performance. During manufacturing, precise control over the window's thickness, surface flatness, and angular accuracy is essential to ensure accurate incidence at the Brewster angle.Brewster windows find extensive use in laser technology. In lasers, they often serve as part of the resonant cavity, helping to control the polarization state of the emitted beam. By positioning the Brewster window so that the laser beam strikes it at the Brewster angle, reflection losses are minimized, thereby enhancing output efficiency. Since the reflected light is linearly polarized, these windows also enable selective control over the laser's polarization direction, meeting diverse application requirements for polarization characteristics.In spectroscopy, Brewster windows play a crucial role as well. When used in spectrometers, they help reduce stray light interference, improving measurement accuracy and spectral resolution. As the reflected light is polarized while stray light typically remains unpolarized, polarization-based filtering techniques can effectively distinguish and eliminate unwanted signals, resulting in cleaner and more reliable spectral data.Company ProfileFUSHI OPTICSTianjin Fushi Optics Co., Ltd. is a comprehensive optoelectronic enterprise integrating R&D, production, sales, and after-sales service.
