Optical Nano Gauge
This page will explain about Taylor Hobson’s “Optical Nano Gauge” used in TDC.
What is Optical Nano Gauge
Optical nano gauge is a film thickness meter provided by Hamamatsu Photonics Co., Ltd., and its official name is “Optical Nano Gauge C13027-11”.
The C13027 is a non-contact film thickness measuring device that uses spectroscopic interferometry, and is compatible with the thinnest 10 nm ultra-thin film measurement in the history of the series. Since high-speed measurement of up to 200Hz is possible, it can also be used for measurement on high-speed lines.
Features of Optical Nano Gauge C13027
● Supports sequencer connection
● Reduced tact time (fastest 200 Hz)
● Supports 10 nm thin film measurement
● Simultaneous measurement of film thickness and color is possible
● Miniaturization (30% reduction in installation area: compared to C12562)
● Wide wavelength support (400 nm to 1100 nm)
● Equipped with simple measurement in software
● Double-sided analysis is possible
● Resistant to height fluctuations
● Optical constant (n, k) analysis
● Supports mapping

Optical Nano Gauge used in TDC
TDC uses the following optical nano gauge models.
・Optical Nano Gauge C13027
Spectral interferometry non-contact film thickness measuring machine
It is used to control the high-precision film thickness. By wrapping it little by little, the processor himself measures it, and by repeating this process, a uniform film thickness is achieved within the same surface.
