Although analytical solutions exist for this simple structure, we have chosen to use the FEM because it can easily be adapted to include the distortions in fabrication unavoidable in realistic structures. FEM has been one of the most accurate methods to investigate the propagation properties of guid ...

Mirror contamination in space I: mirror modelling
... Almost all optical instruments in space suffer from transmission loss due to in-flight degradation of optical components and/or detectors. This transmission loss, especially at shorter Ultraviolet (UV) wavelengths, can, in the worst case, cause a nearly complete loss of detectable photons, and in le ...

Geometrical Optics 101: Paraxial Ray Tracing
... To solve for the effective focal length (EFL), it is first necessary to trace a pseudo marginal ray through the system for an object at infinity (i.e. the first ray angle will be 0). In Figure 9, an arbitrary initial height of 1 is chosen to simplify calculations. Once this is accomplished, the EFL ...

Light sheet-based fluorescence microscopy: more dimensions, more
... The same holds true in confocal fluorescence microscopy. Optical sectioning is not obtained in the illumination process, but by discriminating against the out of focus fluorescence light with a pinhole in front of the detector. Hence, most of the light emitted by the specimen does not reach the dete ...
