This python-packag is about the thin-lens-equation:
1 1 1
--- = --- + ---
f g bThe focal-length of the imaging-optics: f. The image-distance an image has from the aperture’s principal plane: b. The object-distance an object has from the aperture’s principal plane: g. The screen-distance a screen has from the aperture’s principal plane: d.
Note that the screen-distance d is not part of the thin-lens-equation. In case d != b the image on the screen is ‘out of focus’, thus blurred. Only when d == b the image on the screen is ‘in focus’, thus sharp.
Install
pip install thin_lensUsage
import thin_lens
f = 1.0
b = thin_lens.compute_image_distance_for_object_distance(
object_distance=100.0,
focal_length=f,
)
assert b > f
print(b)gives:
