3.3.1.38. NXpinhole

Status:

base class, extends NXobject, version 1.0

Description:

A simple pinhole.

For more complex geometries, NXaperture should be used.

Symbols:

No symbol table

Groups cited:

none

Structure:

depends_on: 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: NX_NUMBER {units=NX_LENGTH}

Size of the circular hole defining the transmitted beam size.
