Infrared Thickness Meter

RX-200 (Film / Coating thickness)



Structure of Liquid Crystal

For determining optical film and various plastic films (PET, PP, PE, PI, PVA, etc.)
Standard online instrument using regular reflection p-polarization method.
Allows highly accurate measurement even for transparent products and ultra-thin films.


Allows selective measurement

Allows selective measurement such as measurement of intermediate layers, sole coating layers, etc.

High response speed and long-term stability

High speed measurement with approximately 50 msec minimum response speed is possible. Ensures long-term accuracy against changes in the ambient environment and instrument fluctuation by using three wavelength photometry.

Target products

Various kinds of films such as PP, PE, PET, PI

Measurement range: 0.1-1000 μm

Measurement accuracy: 0.1 μm
