The principal ray or chief ray (sometimes known as the b ray) in an optical system is the meridional ray that starts at an edge of an object and passes through the center of the aperture stop. [ 5 ] [ 8 ] [ 7 ] The distance between the chief ray (or an extension of it for a virtual image) and the optical axis at an image location defines the ...
Each optical element (surface, interface, mirror, or beam travel) is described by a 2 × 2 ray transfer matrix which operates on a vector describing an incoming light ray to calculate the outgoing ray. Multiplication of the successive matrices thus yields a concise ray transfer matrix describing the entire optical system.
The Physical Optics Propagation feature in Ansys Zemax OpticStudio is useful for modelling systems where coherent diffraction plays a significant role, such as simulating the propagation of laser beams and coupling light into single-mode optical fibers. This tool leverages geometric ray tracing and wave optics.
The phenomenon is studied in the field of gradient-index optics. [4] A ray tracing diagram for a simple converging lens. A device which produces converging or diverging light rays due to refraction is known as a lens. Thin lenses produce focal points on either side that can be modeled using the lensmaker's equation.

Ray tracing of a beam of light passing through a medium with changing refractive index.The ray is advanced by a small amount, and then the direction is re-calculated. Ray tracing works by assuming that the particle or wave can be modeled as a large number of very narrow beams (), and that there exists some distance, possibly very small, over which such a ray is locally straight.
Propagation of a ray through a layer. The transfer-matrix method is a method used in optics and acoustics to analyze the propagation of electromagnetic or acoustic waves through a stratified medium; a stack of thin films. [1] [2] This is, for example, relevant for the design of anti-reflective coatings and dielectric mirrors.
A paraxial ray is a ray that makes a small angle (θ) to the optical axis of the system, and lies close to the axis throughout the system. [1] Generally, this allows three important approximations (for θ in radians) for calculation of the ray's path, namely: [1] , The paraxial approximation is used in Gaussian optics and first-order ...
Lambda Research Corporation (Littleton MA) purchased the program from Sinclair Optics in 2001. The OSLO software is used by scientists and engineers to design lenses, reflectors, optical instruments, laser collimators, and illumination systems. It is also used for simulation and analysis of optical systems using both geometrical and physical ...
