Abstract

1,106,483. Diaphragms. CARL ZEISS JENA VEB. May 6, 1966, No. 20080/66. Headings G2A and G2J. A non-mechanical variable diaphragm the aperture of which instantly adapts itself to any change in brightness has a photo-tropic substance distributed over the aperture so as to provide a zone of highest transmittancy in the centre, and a zone or zones absorption varying directly with the radiation intensity towards the perimeter of the aperture.
