Lampe frontale Cornibert-Klein, photographiée le 6 janvier 1931. Office national des recherches scientifiques et industrielles et des inventions. Ce dispositif est étudié pour l'éclairage pendant la lecture ou l'exécution de toutes sortes de travaux dans l'obscurité. Il peut être fixé facilement au front de l'usager, de sorte que son faisceau suit toujours les mouvements de la tête.

Our work is guided by the way scientists question the world around them and we translate their research into images to help people to understand the world better and to awaken their curiosity and wonderment.
