base class, extends NXobject
Description of an electro-magnetic lens or a compound lens.
For NXtransformations the origin of the coordinate system is placed in the center of the lens (its polepiece, pinhole, or another point of reference). The origin should be specified in the NXtransformations.
For details of electro-magnetic lenses in the literature see e.g. L. Reimer
No symbol table
type: (optional) NX_CHAR
Qualitative type of lens with respect to the number of pole pieces.
Any of these values:
name: (optional) NX_CHAR
Given name, alias, colloquial, or short name for the lens. For manufacturer names and identifiers use respective manufacturer fields.
manufacturer_name: (optional) NX_CHAR
Name of the manufacturer who built/constructed the lens.
model: (optional) NX_CHAR
Hardware name, hash identifier, or serial number that was given by the manufacturer to identify the lens.
description: (optional) NX_CHAR
Ideally an identifier, persistent link, or free text which gives further details about the lens.
Excitation voltage of the lens. For dipoles it is a single number. For higher orders, it is an array.
Excitation current of the lens. For dipoles it is a single number. For higher orders, it is an array.
depends_on: (optional) NX_CHAR
Specifies the position of the lens by pointing to the last transformation in the transformation chain in the NXtransformations group.
MANUFACTURER: (optional) NXmanufacturer
TRANSFORMATIONS: (optional) NXtransformations
Collection of axis-based translations and rotations to describe the location and geometry of the lens as a component in the instrument. Typically, the components of a system should all be related relative to each other and only one component should relate to the reference coordinate system.
