Kurzwelliges Infrarotlicht (SWIR) ist für vieles nützlich: Es hilft, beschädigte Früchte auszusortieren, bei der Temperaturüberwachung und der Kontrolle von Siliziumchips, und es ermöglicht Nachtsichtgeräte mit scharfen Bildern. Doch SWIR-Kameras basieren bislang auf teurer Elektronik. Forscher der Empa, der EPFL, der ETH Zürich und der Universität Siena haben nun einen SWIR-Bildschirm entwickelt, der aus nur acht Schichten auf einer Glasoberfläche besteht. Das könnte Infrarot-Kameras zu nützlichen Alltagsgegenständen machen.
Infrarotlicht (IR) ist für Menschen unsichtbar. Manche Tiere, etwa Klapperschlangen oder blutsaugende Fledermäuse, können IR-Strahlung jedoch wahrnehmen und zur Nahrungssuche nutzen.
