telescope_diffraction_limit

simcado.utils.telescope_diffraction_limit(aperture_size, wavelength, distance=None)

Returns the diffraction limit of a telescope

Parameters

aperture_sizefloat

[m] The diameter of the primary mirror

wavelengthfloat

[um] The wavelength for diffarction

distancefloat, optional

Default is None. If distance is given, the transverse distance for the diffraction limit is returned in the same units as distance

Returns

diff_limitfloat

[arcsec] The angular diffraction limit. If distance is not None, diff_limit is in the same units as distance
