observation window
See-through watching panel
An observation window is a window designed primarily for looking through rather than admitting light or ventilation.
The term appears in technical contexts—a window in a laboratory door, a porthole in a spacecraft, or the glass panel in an incubator allowing medical staff to monitor newborns.
The scientists watched the experiment through the observation window.
