In VirtualLab Fusion, you can design gratings using FMM/RCWA, insert the gratings into a setup with pulsed laser sources for system performance evaluation. Explore the features and functionality of the Ray Optics Module in more detail by expanding the sections below. This website uses cookies to function and to improve your experience. The dispersion coefficients, such as Sellmeier coefficients, can be loaded from a material database or entered directly into a user-defined material. Additionally, the parts can be oriented with respect to previously inserted parts using built-in work planes, and the parts can automatically create named selections to easily assign boundary conditions to the correct surfaces.The refractive index of each medium can be specified directly or derived from an optical dispersion relation. Physical deformations in the optical system, either due to thermal stress or other applied loads, can also significantly affect the image quality. Tutorials. Learning.

If a ray cannot intersect with a surface [ignoring apertures], then a flag is set and the ray trace ceases.

We demonstrate with the examples below.Take part in our upcoming online events. Free Trial Version. Again, to support optical design for illumination systems, it has been necessary to generalize the ray-trace algorithm to include “nonsequential” ray tracing, where the ray determines its trajectory not based upon the ordering of the surfaces in the software database, but instead from the dimensions and locations of the surfaces themselves. These inputs can be adjusted manually or by running a Parametric Sweep study. Building your ideas was never easier with our broad range of tools and products. You can also combine the Ray Optics Module with other add-on modules that offer expanded structural and thermal modeling capability — for example, to account for thermal radiation, conjugate heat transfer, hyperelastic materials, and piezoelectricity.Just click on the "Contact COMSOL" button, fill in your contact details and any specific comments or questions, and submit. An open-source web app to simulate reflection and refraction of light. The flag is now set appropriately. If the ray intensity is solved for, it is automatically updated for the reflected and refracted rays according to the Fresnel equations. Learning. They can also be monochromatic or polychromatic, where you can specify a distribution of wavelengths or enter a set of discrete values.To solve for additional quantities along the ray paths, the After building a ray optics model, there are a host of further opportunities available with the Application Builder that further simplify the simulation workflow.

If you are new to optical software, this can certainly be a confusing time. Especially, we analyze the polarization dependency of such systems.Ultrashort pulses prove helpful in many modern applications.

To manipulate ultrashort pulses, especially for high-power cases, gratings are often employed to either stretch or compress the pulses.

The first thing that you need to know about all of these programs is that their core engines generally fit into one of three categories: sequential ray-tracing; non-sequential ray-tracing; and finite-difference time-domain (FDTD) simulation. Learning. You can also assign conditional boundary interactions or randomly choose between two different boundary interactions with a given probability.At boundaries between dielectric media, each incident ray is deterministically split into reflected and refracted rays.

NEW UPDATE : ray generation function, other bug fix and multiple ray treatment SciPy.

The Ray Optics Module is an add-on to the COMSOL Multiphysics ® software that allows you to model electromagnetic wave propagation with a ray tracing approach. Optical ray tracing library based on MATLAB environment Now working on the simple raytracing simulation. Polarization-insensitive designs are possible with an appropriate selection of the types of nanopillars as the unit cells for the metagrating.
