Description:

description for a fresnel zone plate

Symbols:

No symbol table

Groups cited:

NXgeometry

Structure:

focus_parameters: NX_FLOAT

list of polynomial coefficients describing the focal length of the zone plate, in increasing order.

outer_diameter: NX_FLOAT {units=NX_LENGTH}

outermost_zone_width: NX_FLOAT {units=NX_LENGTH}

central_stop_diameter: NX_FLOAT {units=NX_LENGTH}

fabrication: NX_CHAR

how zone plate was manufactured

Any of these values: etched | plated | zone doubled

zone_height: NX_FLOAT {units=NX_LENGTH}

zone_material: NX_CHAR

Material of the zones themselves

zone_support_material: NX_CHAR

Material present between the zones. This is usually only present for the “zone doubled” fabrication process

central_stop_material: NX_CHAR

central_stop_thickness: NX_FLOAT {units=NX_LENGTH}

mask_thickness: NX_FLOAT {units=NX_LENGTH}

mask_material: NX_CHAR

If no mask is present, set mask_thickness to 0 and omit the mask_material field

support_membrane_material: NX_CHAR

support_membrane_thickness: NX_FLOAT {units=NX_LENGTH}

(geometry): NXgeometry
