Ray Optics Module Updates

For users of the Ray Optics Module, COMSOL Multiphysics® version 6.2 brings a new Elliptical option to the Gaussian Beam feature and introduces more than 90 new glasses in the Optical material library as well as a new tutorial model. Read more about these updates below.

Release Gaussian Beam with Elliptical Cross Section

The Gaussian Beam feature can now be used to define the cross section of a released beam of rays for 3D models. In the Settings window, you can choose between a Circular or Elliptical cross section. The Circular option is equivalent to the functionality provided in previous versions for circular beam cross sections. With the new Elliptical option, you can specify the ratio between the major and minor axes of the ellipse in the Aspect ratio field that appears, and you can specify the orientation of the major axis with perpendicular reference to the beam axis in the Major axis direction field. The major axis always refers to the diameter of the corresponding circular cross section. The Elliptical option gives you the flexibility to model beams that are not perfectly axisymmetric.

Optical Material Library Updates

Within the Optical material library, available in the Ray Optics Module and the Wave Optics Module, more than 90 new glasses from CDGM Glass Co., Ltd. have been added. The new glasses contain all of the necessary properties to perform structural-thermal-optical performance (STOP) analysis.
