QLI Lab at UIUC reveals epi-GLIM for imaging opaque structures

Researchers in the QLI Lab at UIUC Beckman Institute, lead by Prof. Gabriel Popescu have developed a new technique for label-free phase imaging modality applicable to bulk or opaque samples: epi-illumination gradient light interference microscopy (epi-GLIM) (Nature Communications original). Epi-GLIM enables studying turbid structures that are hundreds of microns thick and otherwise opaque to transmitted light. The technique was demonstrated with a variety of man-made and biological samples that are incompatible with imaging in a transmission geometry: semiconductors wafers, specimens on opaque and birefringent substrates, cells in microplates, and bulk tissues. Look for epi-GLIM soon in Phi Optics instrument portfolio!
