The F54-XY comes in a variety of wavelength configurations, allowing it to work with a diverse range of film thickness measurement applications. Usually, thinner films need shorter wavelengths for ...

Measure the length of as many half wavelengths (loops) as possible, divide by the number of half wavelengths (loops). This is half the wavelength, doubling this gives the wavelength. The frequency ...

The remarkable thing about our universe is that it’s possible to explore at least some of its inner workings with very simple tools ... measuring the voltage at which LEDs of various wavelengths ...
