Interferometer

Weißlichtinterferenz​ - Dickenmessung

White light is reflected differently from the upper and lower boundary surfaces of thin films. The reflected light waves are overlaid; they interfere. This interference is related to the coating thickness and can be measured with a spectrometer.

Different measuring ranges are covered by different types of light. The white light interference meter is especially suitable for transparent layers and film.
