At boundaries between dielectric media, each incident ray is deterministically split into reflected and refracted rays. Total internal reflection is also detected automatically. If the ray intensity is solved for, it is automatically updated for the reflected and refracted rays according to the Fresnel equations. You can also define thin dielectric layers on material discontinuities, which can be used as filters, antireflective coatings, or dielectric mirrors.

Glasscutting machine

Rays can be initialized by entering their coordinates directly, importing the coordinates from a text file, or releasing rays from selected geometric entities. Rays can be released from any selection of domains, boundaries, edges, or points in the geometry. There are also dedicated features to produce solar radiation at a specified location on Earth's surface or to release reflected or refracted rays from an illuminated boundary.

Geometrical optics can be used to model electromagnetic wave propagation in optically large structures. The Geometrical Optics interface includes built-in handling of ray intensity and polarization. The intensity calculation uses a form of Stokes–Mueller calculus that makes it easy to keep track of fully polarized, unpolarized, and partially polarized rays.

The COMSOL Multiphysics® software also provides the flexibility to show more than just ray paths, with other dedicated plots to view interference fringes and to decompose optical path difference into individual monochromatic aberration terms. You can also plot the intersection points of rays with a plane, sphere, hemisphere, or a more specialized surface.

The refractive index of each medium can be specified directly or derived from an optical dispersion relation. The dispersion coefficients, such as Sellmeier coefficients, can be loaded from a material database or entered directly into a user-defined material. The refractive index can be complex, wherein the real part determines the speed of light in the medium, while the imaginary part causes ray attenuation or gain.

CNC glasscutting

As technology continues to advance, CNC glass cutting is expected to become even more sophisticated. Innovations such as laser cutting and improved automation will further enhance the precision, speed, and versatility of this technique. Additionally, integration with smart manufacturing systems and the Internet of Things (IoT) will enable real-time monitoring and optimization of the cutting process.

Microscope calculations are a range of formulas used for digital microscopy applications to calculate the depth of field in microscope, field.

Glass cutting has evolved significantly over the centuries. From traditional hand-held tools to sophisticated machinery, the process of cutting glass has become more precise, efficient, and versatile. One of the most advanced techniques in this field is Computer Numerical Control (CNC) glass cutting.

Thermo-optic dispersion coefficients are also available to adjust the refractive index based on temperature. There is also a temperature-dependent Sellmeier dispersion model that combines the temperature and wavelength dependence into a single set of Sellmeier coefficients, which is especially useful for cryogenic materials.

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.

The Ray Heating interface is used to model electromagnetic wave propagation in optically large systems where the rays and temperature distribution are bidirectionally, or two-way, coupled. The energy lost due to the attenuation of rays in an absorbing medium creates a heat source that is included in the temperature computation.

In addition to the refractive index, many of the optical glasses in the Optical material library also provide structural and thermal properties such as density, Young's modulus, Poisson's ratio, coefficient of linear thermal expansion, thermal conductivity, and specific heat capacity. The inclusion of these structural and thermal properties further facilitates coupled STOP analysis. The internal transmittance of the glass is also tabulated as a function of wavelength, so attenuation of light in the medium can also be predicted.

The Optical material library includes data for glasses from SCHOTT AG, CDGM Glass Company Ltd., Ohara Corporation, and Corning Inc., along with assorted gases, metals, and polymers. For most of these optical glasses, the refractive index is given as a function of wavelength via a set of optical dispersion coefficients.

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. The propagating waves are treated as rays that can be reflected, refracted, or absorbed. This treatment of electromagnetic radiation uses approximations that are appropriate when the geometry is large compared to the wavelength.

At each release position, the rays can be launched in a user-specified direction, or a number of different directions can be sampled from a spherical, hemispherical, conical, or Lambertian distribution.

A flexible ray-tracing algorithm allows the rays to propagate through both homogeneous and graded-index (GRIN) media. They can also be monochromatic or polychromatic, where you can specify a distribution of wavelengths or enter a set of discrete values.

Optical systems can be extremely sensitive to changes in their environment, including high altitudes, space, underwater, and in laser and nuclear facilities. Such optical systems are subjected to structural loads and extreme temperatures. The most accurate way to fully capture these environmental effects is through numerical simulation via a STOP analysis. With the COMSOL Multiphysics® software, you can combine structural, thermal, and optical effects in a single model, so that rays are traced in the thermal-stress-induced deformed geometry while the built-in material models account for temperature-dependence of the refractive index.

For example, you can insert a spherical or conic mirror into the geometry sequence; specify whether the surface is concave or convex; enter its radius of curvature; and then specify the clear diameter, full diameter, and diameter of the flat (if any). These inputs can be adjusted manually or by running a Parametric Sweep study. 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.

Combining the Ray Optics Module with other modules from the COMSOL product suite enables ray tracing in temperature gradients and deformed geometries, allowing for high-fidelity structural-thermal-optical performance (STOP) analysis within a single simulation environment.

Roll Pitch Yaw axes. The concept of Roll Pitch Yaw specifically refers to the movement of aircraft among its axes.

With the COMSOL Multiphysics® postprocessing tools, you have the ability to create both visually pleasing and informative simulation results. You can plot rays as lines, tubes, points, and vectors in 2D or 3D, and color the rays by an arbitrary expression that can vary between different rays and even along each ray's path. When solving for ray intensity, you can also plot polarization ellipses along the rays.

When solving for the ray intensity, it can be initialized either by using an expression or loading a photometric data file (specifically an IES file) into the model. Additional predefined ray release features are available to model blackbody radiation and Gaussian beam propagation.

Rays automatically detect geometry boundaries in their path without the need to specify the order of ray–boundary interactions. When a ray reaches a surface, it can be diffusely or specularly reflected, refracted, or absorbed. You can also assign conditional boundary interactions or randomly choose between two different boundary interactions with a given probability.
