Programmable optical interface provides amazing modeling flexibility

The new programmable optical interface of VirtualLab™ allows the modeling of customized diffractive, refractive and hybrid freeform surfaces. This interface can be used in the Optical Interface Sequence Component for modeling of thick lens arrays with customized lens shape. The modeling of lens arrays by surfaces enables the simulation of lens aberrations, vectorial effects, diffraction and interference effects.

Your Benefit

The amplitude in the focal plane of one lens inside an array is depicted. The array is illuminated by a Gaussian laser beam.
  • Modeling of customized diffractive, refractive and hybrid micro lens surfaces by a programmable interface.
  • Customized surfaces can be defined by adding an equation for defining the height depending on the x, y position into the programmable interface.
  • The programmable interface enables the modeling of lens arrays with customized height profile and lens aperture shapes.
  • Powerful propagation techniques of VirtualLab™ enable the modeling of diffraction, interferences, aberrations and vectorial effects at micro lens arrays.

Selected Features

Modeling of customized micro lens surfaces and apertures by programmable interface. The programmable interface allows the specification of an equation describing the profile height depending on the x,y-positions.

Simulation of diffractive, refractive and hybrid micro lens arrays. Customized scripts enable the modeling of diffractive, refractive and hybrid micro lens arrays. These scripts are called snippets.

Analysis of micro lens array based homogenization systems. Micro lens arrays are often used in homogenization systems for LED or excimer laser light. Combining the simulation of thick micro lens arrays with VirtualLab™`s powerful concepts  for modeling partial coherent light allows the investigation of such homogenization systems. The simulation includes the effects of lens aberrations, diffraction and interference on  resulting homogeneity.

Micro lens arrays are often used in homogenizing systems for LED or Excimer laser light.

Outlook Feature Development

  • Snippet for simulation of refractive micro lens arrays with aspherical lens shape.
  • Snippet for simulation of diffractive micro lens arrays.
  • Snippet for simulation of cylindrical lens arrays.
