Microscopy Center

Located on the first floor of the Calit2 Building, the Microscopy Center is equipped with a state-of-the-art extreme high-resolution scanning electron microscope (FEI Magellan 400 XHR SEM), Dualbeam SEM and focus ion beam (FEI Quanta 3D FEG), high-resolution X-ray diffractometer (Rigaku SmartLab) and Multipurpose X-ray diffractometer (Rigaku Ultima III) that are available to faculty, students and industry users on a recharge basis. These instruments offer materials surface imaging, crystal structure determination, orientation mapping, elemental characterization, particles size, film thickness, strain measurement and TEM specimen preparation. They can examine organic and inorganic samples.

Additionally, six specimen-preparation tools were donated to the lab by South Bay Technology, Inc., a Southern California materials-preparation manufacturing company. The equipment is used to prepare SEM cross sections, deposit high-resolution films onto samples, and clean samples and/or microscope parts. It is valued at more than $125,000. Equipment includes a lapping and polishing system, a lapping fixture, a tripod polisher, a low-speed diamond-wheel saw, an ion-beam sputter-deposition and etching system, and a plasma cleaner. 

In addition to assisting Calit2 researchers with their specimen preparation, the SBT/Calit2@UCI partnership provides other opportunities. The company’s headquarters and manufacturing facility are located in San Clemente, and the lab’s proximity allows SBT to respond quickly to new materials preparation challenges as well as demonstrate the efficiency of their equipment to new customers.

The Microscopy Center also houses the Microsystem Analyzer to measure vibration and surface topography in microscale structures including in-plane vibration, out-of-plane vibration and surface topography in high resolution, all without damaging or even contacting the sample. All measurements are done with light, allowing for more realistic testing of MEMS systems in their intended configurations and operating modes, in less time than previously possible.

Note: Users of the Microscopy Center must first be trained on the equipment before they can sign up for microscope time.
