Lens

The lens here is ideal

class Lens(origin, focal_length: float, radius: float = 0.5, transmission: float = 1.0, **kwargs)

Bases: OpticalComponent

Thin ideal lens with circular aperture.

__init__(origin, focal_length: float, radius: float = 0.5, transmission: float = 1.0, **kwargs)

Parameters:

• origin – Component origin in lab coordinates.

• focal_length – focal length of the lens.

• radius – Circular aperture radius.

• transmission – Intensity scaling applied to transmitted ray.

interact_local(ray)

Apply thin-lens deflection and Gaussian q propagation locally.

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

Render lens outline.

get_bbox_local()

Return local bounding box from circular aperture geometry.
