La Galleria delle Applicazioni raccoglie un'ampia varietà di tutorial e di app dimostrative realizzati con COMSOL Multiphysics in diversi ambiti applicativi, inclusi quelli elettrico, meccanico, fluidico e chimico. E' possibile scaricare i file dei modelli e delle app demo pronti all'uso e le istruzioni step-by-step per costruirli, e utilizzarli come punto di partenza per le proprie simulazioni.
Lo strumento di Ricerca Rapida permette di trovare i modelli che si riferiscono alla propria area di interesse.
Si noti che molti degli esempi qui presentati sono accessibili anche tramite le Librerie delle Applicazioni incorporate nel software COMSOL Multiphysics® e disponibili dal menu File.
The Gregory-Maksutov telescope is a simple catadioptric telescope comprising a spherical corrector lens and a spherical primary mirror. In this example the corrector lens and mirror are formed using the 'Spherical Lens 3D' and 'Spherical Mirror 3D' parts respectively from the Ray Optics ... Per saperne di più
A Luneburg lens is a type of graded index, or GRIN lens, in which the gradient of the refractive index leads to special focusing properties. This example model uses the Geometrical Optics interface to compute the curved ray trajectories in the graded-index medium. Per saperne di più
The Hubble Space Telescope (HST) is an example of a standard Cassegrain telescope. The Conic Mirror On Axis 3D part from the COMSOL part library is used to construct the HST Ritchey-Chretien geometry. Multiple release features are used to generate on and off-axis ray and spot diagrams. Per saperne di più
A Fresnel lens can be constructed from a plano-convex lens as a way to reduce the thickness. This model models the collimation property of a Fresnel lens and demonstrates the geometry operation of making a Fresnel lens from a plano-convex lens. Per saperne di più
This example demonstrates how to import a bitmap which can be used to simulate an image using ray tracing. The example is based on the Double Gauss Lens tutorial from the Ray Optics Module Application Library. The first study has been modified so that the Spot Diagram "auto-focus" tool ...

In this model, two concave mirrors are placed at a distance and a ray is released from a point inside the cavity. Then the ray is traced for a predefined time period that is sufficiently long. Ray tracing continues until the predefined computation time has passed if the laser cavity is ... Per saperne di più
In this example, a simple ultraviolet (UV) water purification reactor is modeled using a combination of ray tracing, computational fluid dynamics, and Lagrangian particle tracking. First, the volumetric fluence rate is accumulated along rays released from the surface of the UV lamp using ... Per saperne di più
This type is one of the most popular laser cavities. In particular, it is often used for the Ti-doped sapphire femto-second laser. The stability of the laser cavity is analyzed by releasing a ray inside the cavity and is traced for a predefined time period that is sufficiently long. ... Per saperne di più
This model and tutorial demonstrates the use of an Application Method to compute and plot the geometric Modulation Transfer Function (MTF) for the Petzval Lens. Per saperne di più
The capability to alter the polarization of light is crucial to a wide variety of optical devices. For example, the polarization of light has a significant effect on the performance of optical isolators, attenuators, and beam splitters. By assigning a specific polarization to light, most ...
