Advanced PSF/MTF

The latest technological advances make a requirement of overstepping the traditional understanding of PSF/MTF calculations, where a perfectly round aperture is assumed to be homogeneously illuminated. VirtualLab Fusion envisages fast calculation of realistic PSFs/MTFs

  • for arbitrarily shaped apertures
  • for inhomogeneous illumination of the aperture
  • for high-NA systems
  • for off-axis incidence
  • automatically including vectorial effects

VirtualLab Fusion is able to produce these results in both ray tracing and physical optics form.
