This Brewster Window holder is the solution for your high and low-pressure optical experiments with our state-of-the-art Brewster Window Holder. A Brewster window is a specific type of optical component used primarily in laser applications. It is designed to minimize light loss at a particular wavelength when the light passes through the window. Moreover, the light passing though this window will be polarized to the plane it is traveling through. Brewster Windows have the following unique features:

  1. Optimal Angle: The window is set at Brewster’s angle — a specific angle at which light with a particular polarization will pass through the material with zero reflection. This angle is determined by the refractive index of the material.
  2. Polarization: When light at Brewster’s angle enters the window, it becomes polarized. This means that the light waves vibrate in a single plane, which is particularly useful in laser applications where controlling the polarization of light is important.
  3. Minimizing Loss: By reducing reflection losses, a Brewster window allows more light to pass through, which is crucial for maintaining the efficiency and power of the laser system.
