We present a new design for a confocal rheoscope that enables uniform uniaxial or biaxial shear. The design consists of two precisely positioned parallel plates with a gap that can be adjusted down to 2 ±0.1 μm, allowing for the exploration of confinement effects. By using our shear cell in conjunction with a biaxial force measurement device and a high-speed confocal microscope, we are able to measure the real-time biaxial stress while simultaneously imaging the material three-dimensional structure. We illustrate the importance of the instrument capabilities by discussing the applications of this instrument in current and future research topics in colloidal suspensions. © 2014 AIP Publishing LLC.Citation

The authors would like to acknowledge J. Mergo, T. Beatus, and Y.-W. Lin for technical help and useful discussions on apparatus design. Because this technique took years to develop many individuals contributed to its design. The original prototype was developed by I. C. in collaboration with T. G. Mason and D. A. Weitz. The current version of the multiaxis piezo actuator and uniaxial FMD were developed by J. H. M., J.N.I., and I. C., the biaxial shear protocols and FMD were developed by N.L., J.N.I, and I. C. In addition, the arduous work of developing mechanical and optical calibrations, method development, and developing operating procedures were worked on by N.L., X. C., B. L., and J. H. M.
