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 Rowland circle is a circle of radius R that lies tangent to a concave curved diffraction grating of radius 2R. If the entrance slit of incoming light is positioned on this circle, then rays reflected by the grating will be focused at various points along the same circle based on ... 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
This model demonstrates how to compute the volumetric fluence rate in an ultraviolet (UV) reactor. The geometry is the annular fluid region surrounding a cylindrical lamp. The effect of reflection at the reactor walls on the radial fluence rate distribution is considered. Per saperne di più
This model demonstrates how the sun causes 1.75 arcseconds of deflection for rays grazing the sun's surface as observed from the earth. Einstein predicted this value after refining his theory of relativity during World War I. Per saperne di più
An interesting question was raised in the 1950s by the mathematician Ernst Straus that, in an arbitrarily shaped empty room with side walls made of perfect mirrors, will a point light source always illuminate the whole room? This question was answered by the Nobel Prize-winning ... Per saperne di più
Light Detection And Ranging (LIDAR) is used extensively in self-driving cars to perform the quantitative ranging of the surroundings obstacles. The LIDAR system consists of a laser beam which gets broadened using a MEMS mirror with a particular horizontal and vertical field of view ... Per saperne di più
Freefrom optics has generated renewed interest due to advances in fabrication and manufacturing technology. In this Application Library example, we are going to look at a specific design called the Alvarez lens where two complementary conic surfaces are shifted laterally with respect to ...

Light collimation or focusing is a basic task often needed when working with lasers in the lab where singlets are used due to their simplicity. If a plano-convex lens is used for the task, there is a correct lens orientation that minimizes aberrations. A useful rule-of-thumb is to ... Per saperne di più
