Opticians use rotating ground glass to limit coherence length
Milk has to be fresh each morning, you know.

Ordinary and simple-minded opticians, yes. Jawohl.

Astute and ingenious opticians, no.

Anyway as explained I did switch to a colloidal solution
which lasts forever.

Milk is more easily available however.

A rotating ground glass does not work as well to get rid of
diffraction artefacts, takes more space, requires a motor, a
mount, a fixture etc.

Been there, done that.
