finesse.components.surface.Surface.Rc

property Surface.Rc

The radius of curvature of the mirror in metres, for both the tangential and sagittal planes.

Getter:

Returns values of both planes’ radii of curvature as a numpy.ndarray where the first element is the tangential plane RoC and the second element is the sagittal plane RoC.

Setter:

Sets the radius of curvature.

Examples

The following sets the radii of curvature of an object m, which is a sub-instance of Surface, in both directions to 2.5 m:

>>> m.Rc = 2.5

Whilst this would set the radius of curvature in the x-direction (tangential plane) to 2.5 m and the radius of curvature in the y-direction (sagittal plane) to 2.7 m:

>>> m.Rc = (2.5, 2.7)
