Abstract

In the context of this review, an optical window is a solid barrier with a principal function of transmitting some portion of the electromagnetic spectrum between the short wave atmospheric cutoff of 180 nanometer wavelength and the 12 micrometer thermal infrared. Uses range from protection of optical instruments against hostile natural environments to containment of exceptional man-made environments for study (e.g., combustion) or for production of special forms of energy (e.g., lasers). Flat, uniform thickness panels are most common. Spherical segments and conical elements have found use. Other curved elements and multiple flat glazings are often used to better conform to the shape of a vehicle or other enclosure.

Application of such barriers requires that we examine the effects, other than the desired unimpeded and undistorted transmission, which may be introduced.
