Spectral Analysis of reflections from the surface and the backside of a layer provides information about thichness, refractive index and extinctioncoefficient.

Our Electronic thickness gauges operate on the principle of measuring the capacitance formed between the face of the capacitance probe sensing element and the target surface. The interruption of this field by a dielectric material predictably changes this capacitance based upon the dielectric constant of the material. This change is recorded as a direct voltage change. Our exceptionally stable and linear sensors and signal processing capture and convert this voltage change into thickness or mass units of measure.

We mostly use laser triangulation measuring techniques. Lasers offer an extremely accurate thickness and 'displacement' measurement technique. However, to work properly, particular attention must be given to laser selection, signal processing, calibration, linearization, mounting, the material you are measuring, and process speed, if applicable. We have the experience necessary to maximize laser performance and has developed unique solutions for thickness and 'displacement' measuring; these include gauge and fixture linearization, temperature compensation, EZcal-ibratoin, and integrated fixture design.
