Windows are optical glass with ground and fine polished
faces that are negatively parallel. They are used to
isolate different physical environments while allowing
light to pass.
When selecting windows you should consider the following
properties: tranmission; scattering; wave front distortion;
parallelism and resistance to certain environment.
