  We present a new technique for obtaining simultaneous multimodal quantitative
phase and fluorescence microscopy of biological cells, providing both
quantitative phase imaging and molecular specificity using a single camera. Our
system is based on an interferometric multiplexing module, externally
positioned at the exit of an optical microscope. In contrast to previous
approaches, the presented technique allows conventional fluorescence imaging,
rather than interferometric off-axis fluorescence imaging. We demonstrate the
presented technique for imaging fluorescent beads and live biological cells.
