Matches in DBpedia 2015-10 for { ?s ?p "PSF Lab is a software program that allows the calculation of the illumination point spread function (PSF) of a confocal microscope under various imaging conditions. The calculation of the electric field vectors is based on a rigorous, vectorial model that takes polarization effects in the near-focus region and high numerical aperture microscope objectives into account.The polarization of the input beam (assumed to be collimated and monochromatic) can be chosen freely (linear, circular, or elliptic). Furthermore, a constant or Gaussian shaped input beam intensity profile can be assumed. On its way from the objective to the focus, the illumination light passes through up to three stratified optical layers, which allows the simulation of an immersion oil/air (layer 1) objective that focusses light through a glass cover slip (layer 2) into the sample medium (layer 3).
