NXfresnel_zone_plate¶
Status:
base class, extends NXobject
Description:
A fresnel zone plate
Symbols:
No symbol table
- Groups cited:
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.
focus_parameters[]: (optional) NX_FLOAT
list of polynomial coefficients describing the focal length of the zone plate, in increasing powers of photon energy, that describes the focal length of the zone plate (in microns) at an X-ray photon energy (in electron volts).
outer_diameter: (optional) NX_FLOAT {units=NX_LENGTH}
outermost_zone_width: (optional) NX_FLOAT {units=NX_LENGTH}
central_stop_diameter: (optional) NX_FLOAT {units=NX_LENGTH}
fabrication: (optional) NX_CHAR
how the zone plate was manufactured
Any of these values:
etched|plated|zone doubled|otherzone_height: (optional) NX_FLOAT {units=NX_LENGTH}
zone_material: (optional) NX_CHAR
Material of the zones themselves
zone_support_material: (optional) NX_CHAR
Material present between the zones. This is usually only present for the “zone doubled” fabrication process
central_stop_material: (optional) NX_CHAR
central_stop_thickness: (optional) NX_FLOAT {units=NX_LENGTH}
mask_thickness: (optional) NX_FLOAT {units=NX_LENGTH}
mask_material: (optional) NX_CHAR
If no mask is present, set mask_thickness to 0 and omit the mask_material field
support_membrane_material: (optional) NX_CHAR
support_membrane_thickness: (optional) NX_FLOAT {units=NX_LENGTH}
TRANSFORMATIONS: (optional) NXtransformations
“Engineering” position of the fresnel zone plate
