ABSTRACT:
A continuously variable microdiaphragm has an aperture (3) which has a cross section and which has a shape which remains the same when the aperture becomes greater or smaller. The aperture is lozenge-shaped and is bounded by two recesses each disposed in a separable diaphragm strip (1a, 1b; 2a, 2b) Each of these strips is fixed on or forms part of a transmission leg (4, 5, 30, 31). These legs can be shifted symmetrically relative to each other.
