F20 Series

F20s are general-purpose film thickness measurement instruments, and are used in thousands of applications worldwide. Thickness and refractive index can be measured in less than a second. Like all of our thickness measurement instruments, the F20 connects to the USB port of your Windows® computer and sets up in minutes.

The different F20 instruments are distinguished primarily by the thickness measurement range, which in turn is determined by the instrument's wavelength range. The standard F20 is our most popular product.
