class OpticalModel(radius_mode=False, specsheet=None, **kwargs)

Bases: object

Top level container for optical model.

The OpticalModel serves as a top level container of model properties. Key aspects are built-in element and surface based repesentations of the optical surfaces. A sequential optical model is a sequence of surfaces and gaps. Additionally, it includes optical usage information to specify the aperture, field of view, spectrum and focus.

ro_version

current version of rayoptics

radius_mode

if True output radius, else output curvature

specsheet

SpecSheet

system_spec

SystemSpec

seq_model

SequentialModel

optical_spec

OpticalSpecs

parax_model

ParaxialModel

ele_model

ElementModel

map_submodels(**kwargs)

Setup machinery for model mapping api.

This function performs two tasks:

• populating the submodel dict either with attributes or creating a new instance as needed.

• populate a submodel alias dict with short versions of the wordy defining names

The first task must handle these use cases:

• opt_model populated by importing a .roa file

• an opt_model created interactively

• an opt_model initialized by a lens file importer

name()

reset()

listobj_str()

set_from_specsheet(specsheet=None)

save_model(file_name, version=None)

Save the optical_model in a ray-optics JSON file.

Parameters:

• file_name – str or Path

• version – optional override for rayoptics version number

sync_to_restore()

update_model(**kwargs)

Model and its constituents are updated.

Parameters:

kwargs –

possible keyword arguments including:

• build:

  • ’rebuild’: rebuild the model “from scratch”, e.g number of nodes changes

  • ’update’: number of nodes unchanged, just the parameters

• src_model: model that originated the modification

update_optical_properties(**kwargs)

Compute first order and other optical properties.

nm_to_sys_units(nm)

convert nm to system units

Parameters:

nm (float) – value in nm

Returns:

value converted to system units

Return type:

float

add_part(factory_fct, *args, **kwargs)

Use a factory_fct to create a new part and insert into optical model.

add_lens(**kwargs)

Add a lens into the optical model

Parameters:

kwargs –

keyword arguments including:

• idx: insertion point in the sequential model

• t: the thickness following a chunk when inserting

• lens: tuple of cv1, cv2, th, glass_name_catalog, sd where:

  • cv1: front curvature

  • cv2: rear curvature

  • th: lens thickness

  • glass_input: a str, e.g. ‘N-BK7, Schott’ or

    refractive index or index/V-number pair

  • sd: lens semi-diameter

add_mirror(**kwargs)

add_thinlens(**kwargs)

add_dummy_plane(**kwargs)

add_from_file(filename, **kwargs)

add_assembly_from_seq(idx1, idx2, **kwargs)

Create an Assembly from the elements in the sequence range.

rebuild_from_seq()

Rebuild ele_model and part_tree from seq_model.

When in doubt about whether there is a problem with bad data in an OpticalModel, this function can be used to rebuild everything from the sequential model.

flip(*args, **kwargs)

Flip a Part or an Interface range in the optical model.

The flip operation supports several different ways of specifying what is to be flipped.

Args:

• None: This flips the model from ifc 1 to ifc image-1

• idx1, idx2: This flips the model between interfaces idx1 and idx2. Flipping from object to image is disallowed.

• part: This flips the corresponding part in the model

• list: This flips a list of parts in the model

insert_ifc_gp_ele(*descriptor, **kwargs)

insert interfaces and gaps into seq_model and eles into ele_model

Parameters:

• descriptor – a tuple of additions for the sequential, element and part tree models

• kwargs – keyword arguments including idx: insertion point in the sequential model insert: if True, insert the chunk, otherwise replace it t: the thickness following a chunk when inserting

remove_ifc_gp_ele(*descriptor, **kwargs)

remove interfaces and gaps from seq_model and eles from ele_model

remove_node(e_node)
