National Physical Laboratory- Science and Technology in Wartime, Teddington, Middlesex, England, UK, 1944 A general view of the radiation section in the Light Division of the National Physical Laboratory in Teddington. In the foreground, a female scientist works at a piece of apparatus used to test the absorbing properties of materials regarding infra-red and ultra-violet. This is particular important with regard to the development of sunglasses and welding goggles, as the glass used in these items must be able to absorb infra-red and ultra-violet radiation in order to protect the eyes of the wearer.
