Product DescriptionProduct DescriptionBrewster windows is a special end face structure used in external cavity gas lasers, which is designed to reduce the reflection loss of the glass windows at both ends. This window structure places the glass (or quartz) at a certain angle to the optical axis so that the incident angle of the laser beam is equal to the Brewster angle.Key FeaturesHigh TransmittancePolarization SelectivityReducing Reflection LossAt the Brewster Angle, P-polarized light can pass through the window plate completely with almost no reflection loss. This is very important for improving laser efficiency.Brewster Windows naturally only allow light in a specific polarization direction to pass through, making them an effective way to achieve laser polarization control.By utilizing Brewster angles, reflection loss in optical systems can be significantly reduced, especially in laser resonators.Treatment of Reflected LightAny residual reflected light will leave the resonant cavity without causing interference effectsSpecificationMaterial:UVFS, N-BK7Dimensions:from 2mm to 400mm, customized according to requirementsThickness0.2 to 50mm (subject to dimensions)Dimension/Thickness Tolerance:up to 0.02mmParallelism:up to 3arcsecTWD:up to 1/10L PV@633nmSurface Quality:up to 10-5Clear Aperture:>90% centeredCoatings:AR coating from UV-IRApplications1. Laser systemLaser resonator: Brewster Windows are often used in laser resonators to make the polarization state of laser radiation usually p-polarized. This is because P-polarized light has almost no reflection loss at the Brewster Angle, while S-polarized light is partially reflected. This characteristic can effectively control the polarization direction of the laser and ensure its efficient output.Laser protective cover: Using Brewster Windows in the casing of laser equipment can reduce the energy loss of the laser beam when it passes through the window, while maintaining the polarization characteristics of the beam 2. Optical ModulatorBrewster Windows can be used in optical modulators to help control and adjust the polarization state of the light beam, thereby achieving the modulation of optical signals. 3. SpectroscopyIn spectroscopic applications, Brewster Windows can be used in gas or vacuum cells to reduce the reflection loss of light as it passes through these media, thereby enhancing the accuracy of spectral measurements.Company ProfilePackaging & ShippingPACKINGCarton, Blister, Foam
