Parallel windows are also intended for transmissive use. They are no different from other plane optical windows except for their stringent wedge requirement, which is better than 10 arc seconds. These also come in a different range of substrates such as N-BK7, UV Fused Silica, Calcium Fluoride, and Magnesium Fluoride. Parallel windows are available with laser grade surface quality and flatness.
