isochronal
Equal in duration
Isochronal means equal in time or occurring at regular intervals.
The term appears in technical contexts—physics, engineering, physiology—to describe processes that take the same duration or repeat at uniform periods: isochronal vibrations, isochronal muscle contractions.
A pendulum's swing is isochronal regardless of arc length.
Also spelled isochronous, which is more common.
