Abstract
A dimmer for variably adjusting light transmitted through it to a fiber optic bundle from a light source whose own intensity is not to be adjusted. A body has an axial passage for light to pass through. A plurality of opaque vanes is symetrically arranged in the passage. They meet at an apex located on the axis. Each vane has an axis of rotation in a plane normal to the axis and are rotatable to vary the amount of light which is transmitted. These vanes are coordinated for simultaneous and identical rotation.
