A cleanroom vision panel, also known as a cleanroom observation window or viewport, is a specialized component designed for cleanroom environments. It allows occupants or observers to visually inspect processes, equipment, or personnel inside the cleanroom without compromising the controlled environment.

PBSC’s standard double-glazed cleanroom vision panel provides a flush-glazed finish within a polished stainless-steel architrave.

With many of PBSC’s engineered products, the glazed screen has no visible fixings to either side, aiding attention to detail within cleanroom technology.
