CircularPhaseMask

class poppy.CircularPhaseMask(name=None, radius=<Quantity 1. arcsec>, wavelength=<Quantity 1.e-06 m>, retardance=0.5, **kwargs)

Bases: poppy.optics.AnalyticImagePlaneElement

Circular phase mask coronagraph, with its retardance set perfectly at one specific wavelength and varying linearly on either side of that.

name : string

Descriptive name

radius : float

Radius of the mask

wavelength : float

Wavelength in meters for which the phase mask was designed

retardance : float

Optical path delay at that wavelength, specified in waves relative to the reference wavelengt. Default is 0.5.
