Optical MicroGauge

C11011-01

null

The Optical MicroGauge Thickness measurement system C11011 series is a film thickness measurement system utilizing laser interferometry. Allows for high speed measurement at 60 Hz, so it can also be used inline measurement in factories. Combine with the optional mapping system to allow for prototype thickness distribution measurement. It can be used in a wide variety of applications, from monitoring manufacturing processes to quality control.

The C11011-01 measures glass from 25 μm to 2200 μm and from 10 μm to 900 μm.
