Crystal modeling

VirtualLab Fusion provides the tools to analyze effects of  

  • polarization and
  • birefringence

in uniaxial and biaxial crystals. 

Birefringence is a common property of optical crystal materials, whose refractive index is dependent on the direction and polarization of light. This forms the working principle of many polarization-/phase-/direction-manipulating optical devices. VirtualLab Fusion provides the modeling techniques for crystal slabs/rods with general optical anisotropy, which includes both uniaxial and biaxial cases with arbitrarily oriented optic axis. In addition to natural birefringence, stress-induced birefringence is often worth paying attention to in practice. Furthermore, VirtualLab also enables the conversion from measured stress to induced birefringence, from which the possible influence on the optical system can be analyzed.
