Abstract
A shutter for an infra-red imaging camera comprises shaped first and second elements (17, 18) which are movable relative to each other, between open and closed positions. In the open position, the elements (17, 18) overlie each other leaving a clear optical path through the camera. In the closed position, the elements (17, 18) are disposed side-by-side and completely block off the optical path through the camera.
