3.3.1.40. NXpinhole¶
Status:
base class, extends NXobject
Description:
A simple pinhole.
For more complex geometries, NXaperture should be used.
Symbols:
No symbol table
- Groups cited:
none
Structure:
@default: (optional) NX_CHAR
Declares which child group contains a path leading to a NXdata group.
It is recommended (as of NIAC2014) to use this attribute to help define the path to the default dataset to be plotted. See https://www.nexusformat.org/2014_How_to_find_default_data.html for a summary of the discussion.
depends_on: (optional) NX_CHAR
Points to the path of the last element in the geometry chain that places this object in space. When followed through that chain is supposed to end at an element depending on “.” i.e. the origin of the coordinate system. If desired the location of the slit can also be described relative to an NXbeam, which will allow a simple description of a non-centred pinhole.
diameter: (optional) NX_NUMBER {units=NX_LENGTH}
Size of the circular hole defining the transmitted beam size.
