The propagation of a Gaussian beam through an asymmetric optical system results in a generally or "twisted"" astigmatic beam whose elliptical spot rotates as it propagates in free space. A general… (More)

The propagation of a generally astigmatic Gaussian beam through an arbitrary optical system can be expressed solely in terms of coordinate independent transverse ray vectors. With this formulation,… (More)

The determination of the stray radiation in a well-baffled optical system reduces to the calculation of the scattered energy propagated along a few distinct paths. Approximate formulas are derived… (More)

Basic principles of stray radiation suppression are employed in a FORTRAN computer pro-gram that assists in the design of well-baffled axially symmetric optical systems. Called GOSBOP (General… (More)

Stray light transmittance is analyzed. Mathematical models are evaluated. The results of scatter and diffraction are considered separately, and the combined transmittance values evaluated.
