Filmetrics F20 and F40

The Filmetrics F20 and F40 are both optical reflectometers used to measure the thickness of transparent thin films. The F20 is a general purpose film thickness measurement system. The F40 is attached to a microscope that allows film thickness measurement using very small spot sizes.

This tool requires pre-requisite training on other techniques: clean room safety and wet bench training.
