Optical MicroGauge Thickness measurement system
C11011-22W
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 C11011-22W measures glass from 25 μm to 2.9 mm and from 10 μm to 1.2 mm. (Number of measurable layers : Max. 10 layers)
Features
- Measurement of non-transparent (white color) sample by infrared photometry
- Measurement film thickness range (glass): 25 μm～2.9 mm
- High speed measurement at 60 Hz
- Number of measurable layers: 10 layer
- Measurement of pattern-formed wafer or wafer with protective film
- Long working distance
- Mapping function
- External control available
