ZonePlate ComponentA component which models a zone plate by consierding the plate a secondary source and then by means of Monte Carlo sampling, evaluating the Fresnel-Kirchhoff integral implicitly by resampling the beam in a window defined by the focus_xw,focus_yh parameters. Caveat emptor I: this is a computationally heavy component to run. Caveat emptor II: for correct modelling of phase-interference phenomena, detectors used after the ZonePlate should be of the "PSD_monitor_coh" type. The zone plate can be iether circular or linear. In the linear case, the "slits" are along the x-axis.
| Name | Unit | Description | Default | |
| radius | m | The outer radius of the zone plate. Triggers a circular zone plate. Takes precedence over xwidth,yheight. | 0 | |
| xwidth | m | Width of linear zone plate. | 0 | |
| yheight | m | Height of linear zone plate | 0 | |
| L | m | Focal length. | ||
| lambda0 | AA | The nominal wavelength that the zone plate is designed to focus. | ||
| focus_x0 | m | Offset of resampling window along the x-axis. | 0 | |
