Wollensak's Junior shutter was a simple shutter with built-in diaphragm. It could be used with simple achromatic lens or meniscus lens mounted behind the aperture as well as with more sophisticated two-part lens with one part mounted behind and the other in front of the aperture. The shutter offered the exposure-time modes bulb, time, and instant. It had a connector for a flexible pipe for pneumatic remote control.
