Optical windows

Windows are used to allow optical radiation to pass from one environment to another without allowing other components of these environments to mix. Considerations in selecting windows may include transmission, scattering, wave front distortion and resistance to certain environments. The ideal window allows an optical beam to pass from one medium to the next without changing the wavelength distribution of the beam, the transmitted wave front or scatter any of the light out of the beam.

Quartz glass plate is one of the most extraordinary materials used in industry and research. Due to the combination of a number of very specific properties not given by any other material, quartz glass has cleared the way for many high-tech applications.
