Iris Diaphragms

Actuating lever allows diaphragms to be easily and precisely adjusted Double blade versions allow the diaphragm to be completely closed Leaves are made from blackened, tempered steel Outer casing designed for push fit mounting These iris diaphragms are made from tempered and blackened steel leaves mounted in a metal ring. They are fitted with an actuating lever. Each iris has a smooth and continuous operating range. If it is required that the iris can be closed down to zero aperture then it is important to use the dual blade type. These irises have a plain outer casing which is normally mounted in a housing with a slight push fit.
