finesse.components.lens.Lens
¶
Overview
- class finesse.components.lens.Lens(name, f=inf)[source]¶
Bases:
finesse.components.general.Connector
Represents a thin lens optical component with an associated focal length.
- Parameters
name : str
Name of newly created lens.
f : float, optional
Focal length of the lens in metres; defaults to infinity.
Notes
The specified focal length f is only accurate when the lens is attached to spaces with index of refraction close to 1. This component exists so that one can use the intuitive focal length parameter instead of having to set radii of curvature as with e.g.
Mirror
.
Properties
Numeric ABCD matrix in the tangential plane. |
|
Numeric ABCD matrix in the sagittal plane. |
Methods
|
|
|
Returns the ABCD matrix of the lens for the specified coupling. |
|
Actuate on the focal length of the lens with a specified dioptre shift. |
