From: Microfluidic flowmeter based on a liquid crystal-filled nested capillary

Fig. 2

Microscopic images of the empty (a) and LC-filled (b) nested capillaries, (c) transmission spectra of the empty and the LC-filled nested capillaries, (d, e) polarization micrographs of the nested capillary infiltrated with MDA-05-2782 taken at different rotation angles. (WGM: whispering gallery mode, LC: liquid crystal).
