Facilities and equipment

Our laboratory includes a variety of instruments for measuring three dimensional objects at various scales.

 





 

Our scanning instruments include:

  • A Picza (Roland DGA) touch-probe scanner.   This instrument can scan surfaces with a point spacing of 50 µm in x, y, and has a 50 µm z-resolution.  It comes with Dr. Picza software for data visualization and point cloud output.

  • An XSM multi-sensor scanner (Xystum Corp, Turino, Italy) with an integrated OTM3 Laser Head (Dr. Wolf & Beck GmbH, Wangen, Germany). This instrument generates point clouds with a vertical resolution of 10 µm and a minimum lateral sampling interval of 10 µm. The instrument is bundled with digilinePRO post processor software for rendering point clouds and surfaces.

  • A Sensofar scanning confocal profiler with integrated white light vertical scanning interferometer (Solarius). This instrument also generates three dimensional point clouds representing surfaces with a minimum lateral sampling interval is 0.18 µm, and the vertical resolution is 0.005 µm. This microscope is bundled with SolarMap Universal software for rendering point clouds and surfaces and analyzing microtopography using conventional metrological protocols.  We also have ToothFrax and SFrax scale-sensitive fractal analysis software (Surfract).

  • A Sensofar Neox optical profiler with integrated white light confocal and interferometric scanning.  This instrument generates three dimensional point clouds representing surfaces with a minimum lateral sampling interval is 0.11 µm, and a sub-nanometer vertical resolution. This microscope is bundled with Digitial Surf software for rendering point clouds and surfaces and analyzing microtopography using conventional metrological protocols.  We also have ToothFrax and SFrax scale-sensitive fractal analysis software (Surfract).

  • We also have seven computer workstations, with a typical configure including an Intel PC P4 microprocessor, 4 GB RAM, 250 GB hard drive storage and CD/DVD RW  storage. These computers also share a common network drive with terabyte of disk space.
