Abstract
An iris arrangement has first and second annular carrier elements annular elements coaxially arranged and circumferentially interlocked with one another so as to be independently rotatable. A plurality of iris elements each have a first compliant beam element coupled at a first end thereof to the iris element and at a second end thereof to the first annular carrier element, and a second compliant beam element coupled at a first end thereof to the associated iris element and at a second end thereof to the second annular carrier element. Rotatory motion of the carrier elements relative to each other results in substantially radial displacement of each of the iris elements. The plurality of iris elements communicate with one another when disposed in a radially innermost position. A web covers a region between the plurality of iris elements and the circumference of the first and second annular elements.
