Science - Physics / camera lenses, light
German term or phrase: Punktbild
This is in an interview with a man who tests lenses for cameras. I'm putting in a lot of text for context, but he says what the phrase means in the first sentence. What do you do when someone in an interview just goes off on a very specific single word that you don't know how to translate exactly? Anyway, the context is:

Wir nennen diese Energieverteilung kurz ‚Punktbild' und meinen damit die Größe und die geometrische Form dieses kleinen Lichtflecks.

Die Gestalt der Punktbilder ist aber oft sehr komplex. Man verwendet schon seit Jahrzehnten eine Methode aus der Nachrichtentechnik. Dabei beschreibt man nicht die Einzelheiten eines Punktbildes sondern man untersucht bzw. berechnet seine Wirkung auf eine denkbar einfache Objektstruktur: eine Helligkeit, die sich sinusförmig ändert wie die Spannung in der Steckdose, nur eben nicht mit der Zeit sondern mit dem Ort.

Explanation:
Point spread function - Wikipedia
In microscopy, experimental determination of a PSF is usually tricky, due to the difficulty of finding sub-resolution (point-like) radiating sources.
