xwidth | m | ([-inf, inf]) Horiz. dimension of sample, as a width. | 0.01 | |

yheight | m | ([-inf, inf]) vert . dimension of sample, as a height for cylinder/box | 0.01 | |

zdepth | m | ([-inf, inf]) depth of sample | 0.005 | |

R | m | Outer radius of sample in (x,z) plane for cylinder/sphere. | 0 | |

target_x | m | relative focus target position. | 0 | |

target_y | m | relative focus target position. | 0 | |

target_z | m | relative focus target position. | 1 | |

target_index | Relative index of component to focus at, e.g. next is +1. | 1 | ||

focus_xw | m | horiz. dimension of a rectangular area. | 0.5 | |

focus_yh | m | , vert. dimension of a rectangular area. | 0.5 | |

focus_aw | deg | , horiz. angular dimension of a rectangular area. | 0 | |

focus_ah | deg | , vert. angular dimension of a rectangular area. | 0 | |

focus_r | m | case of circular focusing, focusing radius. | 0 |
