BK7 Windows

 

 

 

 

 

Optical windows are used to allow optical radiation to pass from one environment to another without allowing other elements of these environments to mix. And it does not change the wavelength distribution of the beam, the transmitted wave front, nor does it scatter any of the light out of the beam.
