This paper presents a cursory discussion of the visual optical system, its principal characteristics and the means by which they may be specified. A typical visual system will be discussed in detail, illustrating the required breakdown of its specification into two major areas, basic optical characteristics and system image quality. Consideration of the test procedures that will be precipitated by an unduly comprehensive specification leads to a discussion of those characteristics requiring actual testing vs. those that may be adequately proven by design calculations and documentation.
