Optical Imaging and Micromanipulation

Location: Room 333 LRSM Building
Coordinators: Prof. Arjun Yodh

OIM Facility The center is a facility equipped with a wide array of optical microscopy and micro-manipulation systems to meet the needs of structural, dynamical and material characterization of soft matter, including colloids, emulsions, vesicles, liquid crystals and biomolecular materials. The facility contains:

  • Five optical microscopes equipped with high resolution digital video acquisition systems capable of bright field, phase contrast, high speed, and fluorescence microscopy.
  • Three high-speed confocal setups, which can be used to study three-dimensional structure of materials, and biomolecular samples. 
  • One holographic tweezer system based on a Zeiss Axiovert 135 employs focused laser beams to manipulate microscopic objects. A spatial light modulator can generate complex patterns, and enables three-dimensional manipulation.

In addition to microscopy, the center provides other supporting optics equipment that is useful for characterization of soft materials. In particular, the center hosts a laser light scattering apparatus which is useful for angle-resolved static light scattering and photon correlation spectroscopy (i.e. quasi-elastic or dynamic light scattering spectroscopy).
