PointObj

class PointObj(origin, **kwargs)

Bases: OpticalComponent

Degenerate point-like marker component that transmits all rays.

__init__(origin, **kwargs)

Initialize a point object at origin.

interact_local(ray)

Return the same ray to model perfect transmission.

render(ax, type: str, **kwargs)

Render the point marker in 2D or 3D.

get_bbox_local()

Return local bounding box from point surface geometry.

Block

class Block(origin, hole: Surface | None = None, width: float = 1.0, height: float = 1.0, **kwargs)

Bases: OpticalComponent

Opaque rectangular blocker with an optional hole aperture.

__init__(origin, hole: Surface | None = None, width: float = 1.0, height: float = 1.0, **kwargs)

Initialize a blocking rectangle.

Parameters:

• origin – Component origin in lab coordinates.

• hole – Optional surface removed from the rectangle aperture.

• width – Rectangle width along local Y.

• height – Rectangle height along local Z.

interact_local(ray)

Absorb all incident rays.

render(ax, type: str, **kwargs)

Render block outline.

get_bbox_local()

Return local bounding box from rectangle geometry.
