Ray Optics Module

This model shows how to trace rays of unpolarized light through a Newtonian telescope system. The incoming light is reflected off a parabolic mirror onto a flat secondary mirror, which reflects the light into the focal plane. This type of telescope was first invented by Newton in 1668 and is still made today due to its low cost of assembly.

The Ray Optics Module can be used to model electromagnetic wave propagation in systems in which the wavelength is much smaller than the smallest geometric detail in the model. The electromagnetic waves are treated as rays that can propagate through homogeneous or graded media. Because it is not necessary to resolve the wavelength with a finite element mesh, ray trajectories can be computed over long distances at a low computational cost. Rays can also undergo reflection and refraction at boundaries between different media.
