OptiGauge operates on the principle of interferometry, the interaction of reflected light from materials with slightly different Indices of Refraction.

By detecting the slight changes between layers or materials, OptiGauge can quickly and accurately measure the changes between boundaries and generate measurement results with an accuracy of .00004".

The optical probe directs invisible 1310nm infrared light through transparent, translucent or colored materials and sends reflections from each internal surface through the control module to the PC, where highly advanced software provides instant analysis in an easy-to-use graphical user interface.

OptiGauge can measure many different shapes and topographies, simultaneously supporting multiple probes that can be positioned thousands of feet away from each other.
