lentil.Wavefront#

class lentil.Wavefront(wavelength, pixelscale=None, diameter=None, focal_length=None, tilt=None, ptype=None)[source]#

A class representing a monochromatic wavefront.

Parameters:

wavelength (float) – Wavelength in meters
pixelscale (float, optional) – Physical sampling of wavefront
diameter (float, optional) – Wavefront diameter. Default is None
focal_length (float or np.inf, optional) – Wavefront focal length. A plane wave (default) has an infinite focal length (np.inf).
tilt ((2,) array_like, optional) – Radians of wavefront tilt about the x and y axes provided as [rx, ry]. Default is [0, 0] (no tilt).
ptype (lentil.ptype, optional) – Plane type. Default is lentil.none.
