Rotation

class poppy.Rotation(angle=0.0, units='degrees', hide=False, **kwargs)

Bases: CoordinateTransform

Performs a rotation of the axes in the optical train.

This is not an actual optic itself, of course, but can be used to model a rotated optic by appling a Rotation before and/or after light is incident on that optic.

This is basically a placeholder to indicate the need for a rotation at a given part of the optical train. The actual rotation computation is performed in the Wavefront object’s propagation routines.

Parameters:

anglefloat

Rotation angle, counterclockwise. By default in degrees.

units‘degrees’ or ‘radians’

Units for the rotation angle.

hidebool

Should this optic be displayed or hidden when showing the planes of an OpticalSystem?
