Mirror is infinite, when its finite.

[MaximilianHoffmann]

It seem like rays of a parallel ray bundle reflect at the continuation of a mirror surface, even if the radius is smaller than the bundle diameter?

[jordens]

Do you have example code that shows this? propagate(clip=True) should invalidate out-of-area rays.

[MaximilianHoffmann]

What do you think about this example?

import rayopt as ro
import warnings
import numpy as np
%matplotlib inline
# ignore matplotlib and numpy warning each other
warnings.simplefilter("ignore", FutureWarning)
# ignore floating point exceptions
np.seterr(divide="ignore", invalid="ignore")
# by default only print 4 significant digits
np.set_printoptions(precision=4)
